Some competitive examinations allow the use of a calculator but may permit the use of only a calculator of the non-programmable type.

List non-programmable calculators of famous brands like Casio, Sharp, Texas Instruments, and Hewlett Packard.

### Calculators that are programmable:

Programmable calculators can automatically carry out a sequence of operations under the control of a stored program, much like a computer.
Examples of the programmable calculator are in the top picture. These calculators run on a Computer Algebra System (CAS). A CAS helps ensure that complex algebraic functions are automatic and less tedious. As you can see, these calculators also have graphing capabilities. A calculator with graphing capabilities is likely 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 calculator:

- These calculators can store text or alphanumeric data input by a user.
- These calculators can store, manipulate or graph functions entered in symbolic form.
- These programmable calculators can perform operations such as differentiation, definite integration, algebraic expressions, binomial expansion, symbolic differentiation and the solution to a system of equations.
- These calculators are also capable of external communication or Internet connectivity.

The main difference between a programmable and a non-programmable calculator is there is no function button on the non-programmable calculator. Another difference that can be noticed in non-programmable calculators is that they have no
