Two Line Display There are two lines in the display screen as shown in Figure 1-1: Figure 1-1 Display Screen 7 Basic Features The top line of the screen displays operation status, operator symbols, annunciators, and abbreviations of the registers, variables, and menus. Throughout this manual, this line is referred to as the top line. In Figure 1-1, SIN and RPN on the far right are on the top line. The bottom line displays numbers you have entered, or results. Throughout this manual, this line is referred to as the bottom line. When no operations have been entered and no operations are pending, the bottom line of the screen displays 0. This state of the calculator is referred to as the default calculator screen. The Mode Menu: Setting Preferences The Mode menu allows you to customize the calculator. To access the Mode menu, press :u. Press > or < repeatedly to scroll through the menu starting with FIX=2 (the number of digits displayed to the right of the decimal point). Once an item is displayed, press I to cycle through the other options for that setting. To exit the Mode menu, press O. Table 1-1 below lists the items in the Mode menu. 8 Basic Features Table 1-1 Mode Menu Settings Setting Display Description FIX= 2 The current number of digits displayed to the right of the decimal point.

Table 1-2 Changing the Operating Mode Keys Display Description :u Opens the Mode menu, starting with first setting option, FIX=, the number of digits displayed to the right of the decimal point. <<<< < Scrolls to the current setting for the operating mode, Chain. (Press five times) II Selects RPN as the active (Press two times) setting. Note the RPN annunciator to the right. > or < Pressed repeatedly, scrolls through other settings in the menu. The displayed settings are the active settings. 11 Basic Features Table 1-2 Changing the Operating Mode Keys Display Description O Exits the Mode menu and returns you to the default calculator screen. Key Presses and the Shift : Key To activate a key, press and release the desired key. Most of the 20b's keys have two functions: the primary function and the shifted, or secondary function. The primary function is printed on the top of the key. The secondary function is printed on the bevel of the key. To activate the secondary function of a key, press and release : followed by the key with the secondary function printed on the bevel. Unlike the shift key on a typewriter or computer keyboard, it is not necessary to press and hold : while pressing another key. In this manual, commands with secondary key functions are represented by the shift key symbol, :, followed by the key with the secondary function. For example, to activate sine, press :p. 12 Basic Features When : is active, the down arrow annunciator appears on screen, indicating that the next key pressed will execute the secondary function of the key. To cancel an accidental press of :, simply press : a second time. Key commands for example problems are provided throughout the text and in tables. Key symbols are placed in the order they are to be pressed, from left to right. Annunciators Annunciators are symbols that appear in the display as messages, or after certain keys or key combinations have been pressed. Annunciators are special symbols indicating a specific status in the calculator. Table 1-3 lists the annunciators. Table 1-3 Annunciator Symbols Annunciator Symbol (•) Status The shift key has been pressed. When another key is pressed with this symbol displayed, the secondary function printed on the bevel of the key is activated. Big (=) symbol When displayed with an item, for example, Price =, it indicates the value assigned to that variable. 13 Basic Features Table 1-3 Annunciator Symbols Annunciator Symbol Small (=) symbol Status Indicates an item for which the = key is valid. This symbol appears on the upper right of the display screen. Battery power is low. BEG Begin mode is activated. STO Stores a number in memory. RCL Recalls stored numbers. RAD Radians setting is active. RPN RPN mode is active. 360 The 360-day calendar option is active. INPUT Input mode is activated. The I Key The I key is used to input values for variables and execute menu items. 14 Basic Features The I key is also used in Reverse Polish Notation (RPN) mode to enter a number on the stack or duplicate it. The = Key The = key is used at the end of a mathematical operation to calculate the final result. For example, 1+2= returns a final result of 3. The = key also allows you to request a calculation for the value of an item. This request only applies to items that can be calculated. For example, when you select the nominal interest rate (Nom. %= ) in the Interest Conversion (Iconv) menu, pressing = outside of a mathematical operation calculates and displays the nominal interest rate based on the stored data in the other variables in the menu. To open the Iconv menu, press :&. Nom %= displays on the top line, and the current value assigned to the nominal interest rate is displayed on the bottom line. At this screen, press 12I to enter a new current value for the nominal rate. Press < followed by = to calculate the current value for the effective rate. See Figure 1-2. Figure 1-2 15 Basic Features When an item for which the = key is valid displays, the small indicator (=) is displayed on the top line at the right of the screen. Do not confuse this small annunciator (=) with the larger annunciator (=) found to the right of a variable. Editing Entries and Clearing The On/CE O Key Pressing O one time cancels current number entries, mathematical operations, or a menu selection, in that order. Pressing O repeatedly while performing multiple actions or operations, or with multiple operations pending, cancels one operation at a time, from the latest to the earliest. The Reset :x Menu The Reset menu allows you to reset some, or all, of the menu items, variables, and registers to their default values. To open the Reset menu, press :x. TVM displays on the top line. Press < repeatedly to scroll to a specific item. If you select the command to reset all values, All , you will be prompted to confirm your choice. To reset, press At the All Reset message, press O or I. I to exit. Pressing :x while working within a particular menu takes you directly to the item of the Reset menu that allows you to reset that menu. Say, for example, you 16 Basic Features are working in the Bond menu and you wish to reset all your entries in the Bond menu. From anywhere in the Bond menu, press :x. Bond displays on screen. At this prompt, pressing I resets the Bond menu and returns you to the last item you were working with in the Bond menu. Notes about Special Menus The Mode, Memory, Math and Reset menus are special menus, because when you exit them by pressing O, you return to the previous menu (if any). This feature allows you to work in two or more menus simultaneously without having to exit a menu and lose your work. Memory The Cash Flow and Statistics menus share the same memory and are limited to a combined total of 50 memory slots. Macros can record up to 120 keys. Since entering data in menus can represent a significant amount of work, when the reset commands for the macro, cash flows, statistics and delete all (Del.All? ) functions are used, you will be asked to confirm your choice. At the prompt, press I to confirm, or O to cancel. 17 Basic Features Accessing Menus and Menu Maps Many of the 20b's functions are located within menus. To access a menu, press the key, or shift key combination for the menu in which you wish to work. To exit a menu, press O. For example, to access the Break-even menu, press :!. Once opened, you can scroll through the items in the menu by pressing >< repeatedly. When you arrive at the last item in a menu, pressing < returns you to the first item. Similarly, pressing > one time on the first menu item scrolls to the last item in the menu. In this manual, diagrams called Menu Maps are included at the beginning of each section to assist you in navigating through the menus used for that section. For an example of a menu map, see Figure 1-3 below. Figure 1-3 The Menu Map for the Break-even Menu 18 Basic Features There are four types of menu items: 1. Read/write. Read/write menu items, such as Price= in the Breakeven menu shown above, are easily recognizable, because when they are selected, both the INPUT and small (=) annunciators are lit. When lit, these annunciators indicate that entering a number and pressing I will store the entered number in the displayed menu item. pressing = (outside of a mathematical operation) you will then By calculate the value for that item based on data entered elsewhere in the menu. 2. Read-only. Read-only items such as Internal Rate of Return (IRR%= ) in the IRR menu are display-only; they are calculated values computed internally by the calculator. 3. Write-only. Write-only items, such as investment interest rate (Inv. I%= ) in the Net Present Value (NPV) menu, are similar to read/write items in that the INPUT annunciator is lit when these items are selected, indicating that entering a number and pressing I stores that number in that menu item. 4. Special items. Special items, such as the Degree/Radian option in the Mode menu, the items of the Reset menu, and the items of the Percent Calculation (%calc ) menu perform an action when I is pressed. Depending on the menu, this action can be the selection of a sub-menu in the %calc menu, changing a mode or setting in the Mode menu, or erasing data with the Reset menu. 19 Mathematical Calculations 2 Mathematical Calculations Mathematical Functions Mathematical functions are located: On keys, such as, +-*/ etc. On shifted, or secondary functions, such as, :p In the Math menu :s Number Entry and Display Numbers are entered by pressing: Numbered keys, 0-9 The decimal point . The } key The :w keys To correct a number entry, press {. Each press of { erases the last digit or symbol you entered. Change how numbers are displayed on screen with the options in the Mode menu. For more information on calculator display settings, see the section titled, The Mode Menu: Setting Preferences. 20 Mathematical Calculations To enter a number in the display, press the digits successively. A number can have up to 12 digits. To change the sign of a number from positive to negative, press }. Use scientific notation to enter very large and very small numbers. For example, to enter the number 12345.12123 in scientific notation, first enter the mantissa, 12345, then press :w and enter the number representing the exponent, 123. The exponent must have a value between -499 and +499. Chain Mode By default, calculations are performed in Chain mode. To change the calculating mode, refer to the section titled, The Mode Menu: Setting Preferences. Calculations in Chain mode are interpreted in the order in which they are entered. For example, enter the following numbers and operations as written from left to right: 1+2*3. See Figure 2-1. Note how if you press an operator key, +-*/, after =, the calculation is continued using the currently displayed value. Figure 2-1 Calculation in Chain Mode In Chain mode, if you wish to override the left to right order of entry, use parentheses () to prioritize operations. 21 Mathematical Calculations For example, to calculate 1+ (2 x 3), you may enter the problem as written from left to right, with parentheses to prioritize the multiplication operation. See Table 2-1 below. Table 2-1 Simple Arithmetic Calculations in Chain Mode Keys Display Description 1+ (2*3) Sets operational priority, inputs numbers, and multiplies 2 and 3. = Adds 1 to 6 and returns 7.00 on the bottom line as the final result. Algebraic Mode To set the calculator in Algebraic mode, refer to the section titled, The Mode Menu: Setting Preferences. In Algebraic mode, multiplication and division have a higher priority than addition and subtraction. For example, in Algebraic mode, pressing 1+2*3 returns a result of 7.00. In Chain mode, the same key presses return a result of 9.00. In Algebraic mode, operations have the following priority: 22 Mathematical Calculations First priority: the power function (y x) Second priority: combinations and permutations Third priority: multiplication and division Fourth priority: addition and subtraction For example, key in 1+2 x 5 nPr 2 2 in Algebraic mode by pressing: 1+2*5:b2:m=. The result is 241. Reverse Polish Notation (RPN) Mode To set the calculator in RPN mode, refer to the section titled, The Mode Menu: Setting Preferences. In RPN mode, numbers are entered first, separated by pressing I, followed by an operation key. Note: pressing I is optional after entering a number if the next key pressed is an operation. Each time you press an operation or function key, the answer is calculated immediately and displayed. For example, suppose you wanted to add two numbers in RPN, 1 and 2. Press 1I2+. The result, 3.00, is calculated and displayed immediately on the bottom line along with the (+) symbol on the top line. 23 Mathematical Calculations You do not need to enter parentheses to set the priority of your operations in RPN. Key in numbers and operations inside the parentheses first, followed by those outside of the parentheses. If a problem has more than one set of parentheses, start by working with the operations and numbers in the innermost parentheses and work out. For example, calculate: (3 + 4) x (5 + 6). One way to calculate this problem is to key in the numbers and operations within the parentheses first, followed by the operations outside of the parentheses. See Table 2-2 below. Table 2-2 Simple Arithmetic Calculations in RPN Mode Keys Display Description Inputs the numbers and the 3I4+ operation in the first set of parentheses. Intermediate results are displayed. Note the (+) and (RPN) annunciators. 5I6+ Inputs the numbers and the operation in the second set of parentheses. Intermediate results are displayed. Note the (+) annunciator. 24 Mathematical Calculations Table 2-2 Simple Arithmetic Calculations in RPN Mode Keys Display Description * Continues the operation with the displayed results. = Validates the final result of 77. Note the absence of the (*) annunciator. One-Number Functions and the Math Menu The key presses for the one-number mathematical functions listed in Table 2-3 below apply to all modes, Chain, Algebraic, and RPN. To execute one-number functions: 1. Key in a number, x , into the display. 2. Press the key or key combination corresponding to the operation you wish to execute. The results are displayed on the bottom line. For example, to calculate 6 , press 6:n. A result of 2.45 is calculated immediately and displays on the bottom line. The on the top line. 25 symbol appears Mathematical Calculations Note: before doing any trigonometric calculations in the Math menu, check whether the angle mode is set for degrees (Degrees) or radians (Radians). You can change the setting if the active mode is not what your problem requires. For more information on the Mode menu and calculator settings, refer to the section titled, The Mode Menu: Setting Preferences. Table 2-3 lists one-number functions along with their corresponding keys. Table 2-3 Shifted Function Mathematical Operations Keys Description :w Keys in numbers with explicit powers of 10. :p Calculates sine. :q Calculates cosine. :r Calculates tangent. :k Natural log. :l e x. Calculates natural exponent to the power of x. :m X2. Returns square of x. :n Calculates square root. 26 Mathematical Calculations Table 2-3 Shifted Function Mathematical Operations Keys Description :f Executes the Random function. Returns a random number in the range 0 < x <1. :g Calculates factorial of x (where 0 ≤ x ≤ 253). :h y x. Returns y to the x power. :i Reciprocal. :e Rounds x internally to the number specified by the display format. Default is two digits to the right of the decimal point. The Math :s Menu There are additional one-number functions available in the Math menu. To open the Math menu, press :s. See Figure 2-2 for the menu map of the Math menu. 27 Mathematical Calculations Figure 2-2 The Menu Map for the Math Menu 28 Mathematical Calculations Press < to scroll through the menu items, starting with Trigonometry. The Trigonometry, Hyperbolic, and Probability items have sub-menus. Press I with an item displayed to access the functions within the sub menus. Press O to cancel the Math menu and return to current work. Press :s to return to the top of the Math menu. Using the Math menu, calculate Sin -1 (0.5). See Table 2-4. Table 2-4 Math Menu Example Keys Display Description .5I Enters 0.5 and opens the Math :s menu starting with Trigonometry. I< Selects the Trigonometry menu item and scrolls to ASIN. Note the value for Sin -1 is calculated immediately and displayed. I or = Validates the result. Note: in the Math menu, PI does not perform calculations; it overrides the current number by PI. You may start an operation, use the Math menu to execute a 29 Mathematical Calculations function, and continue calculating with your original operation without losing your work. Two-Number Functions Apart from +-*/, the three additional two-number functions accessible on the keyboard are: Yx nCr nPr Y x is the power function; nCr stands for the number of combinations of elements, r, among n, and nPr stands for the number of permutations of elements, r, among n. nCr=n!/(r!(n-r)!) nPr=n!/(n-r)! Perform calculations with these functions in the same way you would perform calculations with +-/ and *, but press : to access the secondary function key. For example, to calculate 15 3 : 1. Press 15. 2. Press :h. 30 Mathematical Calculations 3. Press 3=. The results are shown Figure 2-3. Figure 2-3 In RPN mode, key in the numbers first, followed by I, then press the function key. For example, for the power function example above, in RPN press: 15I3:h. Storing and Recalling Numbers EURO has ten calculation memories available for use during calculations. These memories are numbered from 0-9. To store numbers, press :$; to recall them, press L. You can use the store and recall functions for these memories any time a number is displayed, or when you wish to enter a number. To store a number in a memory: 1. Key in a number, x. 2. Press :$. 3. With STO displayed on the top line, key in a number, 0-9, to identify the number of the memory register where you wish to store x. 31 Mathematical Calculations 4. To recall a number, press L. With RCL displayed in the top line, key in the number of the memory you used. You can also perform operations to stored numbers. For example, press 5:$2 to store 5 in memory 2. To add 12 to the value of memory 2, press 12:$+2. Later on, during a calculation, you can press L2 to recall memory 2. Note how the new current value is 17, (5 +12). +-* and / are valid mathematical operations in the storage memories. Recalling Stored Numbers In RPN, typing 12L+2= adds the value of memory 2 to 12, but it will not modify the stored value of memory 2. You can also use -* and / after L. In Algebraic and Chain modes, press 12+L2=. Rounding Numbers The 20b performs all calculations internally with 15-digit precision and rounds to 12 digits when returning the results. When displayed, a number is rounded to the number of digits after the decimal point set by the FIX= item in the Mode menu. The default setting is two digits to the right of the decimal point. For more information, refer to the section titled, The Mode Menu: Setting Preferences. 32 Mathematical Calculations Note: the FIX= setting only affects the display; it does not affect the actual numbers. Simple Percentages In Algebraic or Chain modes, pressing % divides a number by 100. For example, pressing 25% returns 0.25. To find a percentage of a given number, enter the number and multiply it by the desired percentage, followed by = to return the result. For example, to find 25% of 200, press 200*25%= to return a result of 50. To add or subtract a percentage of a number, enter the first number, followed by + or - the percentage, followed by %. Finish your calculation with =, if desired. For example, to add 10% to 50, press 50+10%= to return a result of 55. In RPN mode, the % key calculates x percent of the number on level two of the stack, when x is the number on level one of the stack. It does not modify the number on level two of the stack, allowing you to perform an addition or a subtraction after pressing % to add or subtract x % from the number. For example, 200I25% returns 50, but 200 is still on level two of the stack, and pressing - returns 150, or 200-25%, with the (-) annunciator displayed on the top line. 33 Statistical Operations 3 Statistical Operations Figure 3-1 The Menu Map for the Data and Statistics Menus 34 Statistical Operations Statistics operations require the use of two secondary function keys: :y and :z. See Figure 3-1 for assistance with navigating through the menus. Press :y to open the Data menu. In this menu, enter a list of x values for one-variable statistics, a list of pairs, (x, w) for weighted, one-variable statistics, or a list of paired values (x, y) for two-variable statistics. To enter data, key in a number and press I. Press :z to analyze the data. If you attempt to open the Statistics (Stats) menu before entering data, you will be redirected to the Data menu. When opened, the menu displays 2 Vars. Press I repeatedly to scroll through the menu items, two-variable, (2 Vars ), one-variable, (1 Var ), and one-variable weighted, (1 Weight ). Press < with an item displayed to open the first submenu. To return from the sub-menu to the menu above it, press >. To reset the Stats and Data menus, press :x.

Each pair represents a single cash flow. CF(n) represents the monetary value of the cash flow; #CF(n) is the number of consecutive occurrences of that cash flow. By default, #CF(n) is equal to 1, as most cash flows occur only once. However, in cases where a cash flow is 50 Cash Flows repeated multiple times in a list, using #CF(n) instead of entering the cash flow value multiple times can save you time and memory space in the calculator. To enter a cash flow list, press C to open the cash flow menu. For each cash flow item, enter the cash flow followed by I; then enter the number of occurrences followed by I. If a cash flow occurs once, you do not need to type 1I; you can simply press I, as 1 is the default. To reset a cash flow list to its default values, with any cash flow displayed, press :x. The number of cash flows in the list, along with Cash Flow= , displays. I. You will be asked to confirm your choice.

Table 8-2 describes the items found in the depreciation sub-menus. For an example calculating depreciation using the straight-line method, see Table 8-3. Table 8-1 Depreciation Methods Depreciation Method Sline Description Straight line is a method of calculating depreciation presuming an asset loses a certain percentage of its value annually at an amount evenly distributed throughout its useful life. SOYD Sum-of-the-years' digits is an accelerated depreciation method based on the idea that the years of an asset's useful life are divided by the sum of the years counting backwards. For example, a five year useful life would be shown as 5 + 4 + 3 + 2 + 1= 15. Press 4 / 15, then press = to return a 27% depreciation for the first year. In RPN, press 4 I 15 /. 75 Depreciation Table 8-1 Depreciation Methods Depreciation Method DecBal Description Declining balance is an accelerated depreciation method that presumes an asset will lose the majority of its value during the first few years of its useful life. DBXover Declining balance crossover is an accelerated depreciation method that presumes an asset will lose the majority of its value in the first few years of its useful life, but that it will revert to a consistent depreciation during the latter part of its life, which is then calculated using the straight line method. ACRS Accelerated Cost Recovery System calculates the amount of tax deduction under U.S. Accelerated Cost Recovery System. Sl Fr Straight line French. This method of depreciation is similar to the Straight line method, except an actual calendar date in mm.dd format is entered in for Start= to indicate when the asset was first placed into service. 76 Depreciation Table 8-2 Depreciation Menu Items Item Description Life= The expected useful life of the asset in whole years. Start= Start refers to the date or month in which the asset is first placed into service. Depending on the type of depreciation, this can be the month, or the actual date in mm.dd format. Cost= The depreciable cost of the asset at acquisition. Salvage= The salvage value of the asset at the end of its useful life. Year= Assigns the value of the year for which you want the depreciation. Depreciation= Depreciation calculation used for straight line, SOYD, and declining balance methods only. R.Book Value= Remaining book value. R.Depreciable Value= Remaining depreciable value. 77 Depreciation Table 8-2 Depreciation Menu Items Item Description Factor= The declining balance factor as a percentage. This is used for declining balance and declining balance crossover methods only. A metalworking machine, purchased for $10,000.00, is to be depreciated over five years. Its salvage value is estimated at $500.00. Using the straight-line method, find the depreciation and remaining depreciable value for each of the first two years of the machine's life. See Table 8-3. Table 8-3 Straight Line Depreciation Example Key Display Description :\ Opens the Depreciation menu starting with the straight line method. < Displays the current value of the useful life. 1 is the default value. 5I Inputs 5 as the current value for the useful life. 78 Depreciation Table 8-3 Straight Line Depreciation Example Key Display Description < Displays the current value of Start=. 1 is the default value. < Displays the current value for Cost=. 1000 0I Inputs the current value for cost as < Displays the current value for 10,000.00.
