Calculators that are NOT programmable: This is what a non-programmable calculator looks like. List of non-programmable calculators of some famous brands like Casio, Sharp, Texas Instruments, Hewlett Packard. Calculators that are programmable: This is what a programmable calculator looks like. These calculator runs on a Computer Algebra System (CAS). A CAS helps to make certain difficult algebraic functions automatic and less tedious. As you can see, these calculators also have graphing capabilities. A calculator with graphing capabilities is most likely to be programmable. The easy way to tell if the calculator has graphing capabilities is by looking at the larger screen than would be found on a scientific calculator. Features of Programmable calculators: 1. These calculators are capable of storing text or alphanumeric data input by a user. 2. These calculators are capable of storing, manipulating or graphing functions entered in symbolic form. 3. These programmable calculators are capable of performing for operations such as differentiation, definite integration, algebraic expressions, binomial expansion, symbolic differentiation and the solution to system of equations. 4. These calculators are capable of external communication or Internet connectivity. 5. These calculators display a matrix and vector function key. 6. 7. These calculators allow use of the full alphabet from A-Z. These calculators tend to be bulky and heavy in comparison to nonprogrammable calculators.
