RPN Tip #2
Å Previous – Article – Next Æ
Human data entry is error prone and this is primary reason machine readable bar codes are used on
nearly everything these days. The four-high automatic RPN stack is easy to master and it may be used to
avoid having to enter numbers related to a problem more than once.
Suppose you need to evaluate the expression (A2 + 3A) ÷ 1.3 with an A value of 2.918273645. You
could solve the problem three ways.
You could press 2.918273645, ENTER, ENTER,
(seven keystrokes)
to calculate
2. The experienced RPN user would press 2.918273645, X^2, LASTX, 3, ×, +, 1.3, ÷ to calculate
13.2854938478. (six keystrokes)
The latter method disturbs the stack less and uses fewer keystrokes.
3. The more math minded (student?) would recognize that the algebraic “problem” could be transposed to
A( A + 3 )
and press 3, ENTER, 2.918273645, +, LASTX, ×, 1.3, ÷ to calculate 13.2854938478.
(five keystrokes)
NOTE: The above “keystroke counts” or the method of counting is not clear. Because numbers may range
from a single digit to 10, 12, or more digits, and these digits would be the same for any machine, they are
not counted as keystrokes. To clarify this issue the following is offered.
Counting Keystrokes
RPN Tip #2 showed three RPN methods to solve a problem. Each successive method improved on the
method before it in terms of the “efficiency” of the solution. This efficiency is the number of calculator
operation keys that have to be pressed to solve the problem. The number of keystrokes is related to three
1. The RPN machine being used. Some RPN operations are shifted keys. R , for example, is shifted on
the HP35s and several of HP’s legacy RPN calculators. Shifted operations require two keystrokes.
2. The order of the operations and the utilization of the RPN automatic stack operations.
3. The mathematical form that is used to express the problem. If the problem is represented by an
algebraic expression, for example, the calculator solution is having the expression rearranged for a
more efficient calculator keyboard solution. Complete books have been written on the topic of
(optimum) “calculator solutions.”
Keystroke counting is the only objective measure of comparing the problem solving efficiency of one
machine to another or one solution method to another. In order to keep everything on a level playing field
the keystrokes required for entering the data (numbers) are not counted. This is illustrated using solution
number three of RPN Tip #2.
4. The more math minded (student?) would recognize that the algebraic “problem” could be easily
transposed to be:
A( A + 3 )
And press 3, ENTER, 2.918273645, +, LASTX, ×, 1.3, ÷ to calculate
keystroke number
13.2854938478. (Total of five keystrokes).

Is it raining again in Seattle…
Wait, you mean San Antonio
Å Previous – Article – Next Æ
Here are two quick problems involving fractions and number patterns. Both of these problems involve
trends in the average annual rainfall of a US city. These trends are called 50-year trends and are based on
data gathered by the National Oceanic and Atmospheric Administration (NOAA).
Two Rainy Cities?
Seattle has long been known for its cloudy, rainy weather; in fact, one of its nicknames is the Rainy City.
Since 1961, the average annual precipitation has been just less than 38 2/5”. San Antonio, on the other
hand, had an average annual precipitation of just less than 30 1/2" over the same period. According to
NOAA, San Antonio has a 50-year trend of increasing annual precipitation. If the trend continues,
eventually San Antonio will have greater annual precipitation than Seattle currently has. The trend is an
additional 1 1/8” of precipitation per decade. Use this information to fill in the first column in the table
below. Then estimate the year in which San Antonio’s annual precipitation is greater than Seattle’s current
38 2/5”.
Two Trends
Seattle, in the meantime, has its own 50-year annual precipitation trend. According to NOAA, the trend
for Seattle is a decreasing one. Seattle gets 2/3” less annual precipitation each decade. With Seattle’s
annual precipitation decreasing and San Antonio’s increasing, at some point the two cities will have the
same annual precipitation. Fill in the second column of the table below with rainfall figures. Estimate the
year in which both cities have the same annual precipitation. Show your estimate of the number of inches
of rainfall that year as well.

Teacher Notes
These short activities take global warming and climatic change as topics to generate student interest in
mixed numbers and number patterns.
Glencoe Mathematics Series
In Texas Mathematics, Course 1, these activities can be used at the end of Chapter 5 (5.6 and 5.7) as
students investigate adding and subtracting mixed numbers. They can also be used in Chapter 6 (6.5 and
6.6) as students investigate arithmetic sequences. In either case, the two activities are best kept together.
As an investigation of arithmetic sequences, you can also use these activities with Course 2, Chapter 1 and
with Course 3, Chapter 10.
The following TEKS can be found in this activity set. The TEKS are listed in grade-level order, not the order
in which they appear in the activities. Also, some of the TEKS statements are abbreviated or paraphrased
The student is expected to:
• 6.1(A) compare and order non-negative rational numbers (also 7.1(A) and 8.1(A))
• 6.2(B) use addition and subtraction to solve problems involving fractions and decimals (also 7.2(B)
and 8.2(B))
• 6.2(D) estimate and round to approximate reasonable results and to solve problems where exact
answers are not required
• 6.4(A) use tables and symbols to represent and describe proportional and other relationships such
as those involving conversions, arithmetic sequences (with a constant rate of change), perimeter,
and area
• 6.11(D) select tools such as real objects, manipulatives, paper/pencil, and technology or
techniques such as mental math, estimation, and number sense to solve problems (also 7.13(D) and
Web Resources
The information for this exercise was adapted from the web site of the National Oceanic and Atmospheric
Administration, or NOAA. From their home page, scroll down a bit and click on the Climate icon. From
there, you can get information on many US cities, including Seattle and San Antonio.
Answer Key for Two Rainy Cities
In this activity, students learn about precipitation trends predicted by the National Oceanic and
Atmospheric Administration (NOAA) for San Antonio. These trends indicate that San Antonio will
eventually have greater annual precipitation than Seattle currently has. Will San Antonio be the next
“Rainy City”? This activity uses the Mixed Fraction mode to operate on mixed numbers, as well as the ANS
function to create number patterns.
1. Go to Modes menu and change Number Format to Mixed Fractions, with an accuracy level of 4 (see
Figure 1). Then return to the Home screen.
2. Enter the current annual precipitation figure for San Antonio: 30.5”. Note that the HP 39gs changes the
decimal to a mixed number, 30+1/2, as in Figure 2.
3. Press the + key and the HP 39gs will enter “ANS +” with the cursor positioned after the + sign. ANS
represents the last ANSwer (30 ½), so type in 1+1/8 (Figure 2) and press ENTER to see the annual
precipitation for 2017 (one decade later).
4. Press ENTER repeatedly to see the model’s predictions for 2027, 2037, etc. Look carefully as you press
ENTER and you will see that the annual precipitation reaches 38 3/8 in 2077. This is just under Seattle’s
38 2/5. How much less? Just 1/40”! See for yourself by subtracting 38+2/5 from 38+3/8.
Extension: If the annual precipitation increases by 1 1/8” in 10 years, how long will it take to increase
by 1/40”? You should find it to be 2 2/3 months.
Figure 1: Mixed Fraction format
Figure 2: 30.5 becomes 30 1/2
Figure 3: The first two terms, using ANS
Figure 4: 38 3/8” in 2077
Answer Key for Two Trends
In this short activity, students match the increasing trend of San Antonio precipitation to the decreasing
trend of Seattle precipitation to estimate the year in which both cities have the same amount of rainfall.
1. Repeat the same process on the HP 39gs, but with an initial starting value of 38 2/5 (see Figure 5)
and a decrease of 2/3 (Figure 6). The values are shown in the table below.
Figure 5: Starting the Seattle sequence
Figure 6: Using ANS again
San Antonio
Looking at the table, it is clear that the two cities would be predicted to have identical rainfall totals in one
of the years between 2047 and 2057. This is definitely within the life expectancies of the students!
