We focus on the Casiofx-82 because the majority of students possess this calculator, note that calculators from other manufacturers have the same functionality, we will focus on the following

- Prime Factors
- Table Mode - input functions and output tables
- Stat Mode - input coordinates and output equations
- Memories - enter function as variables and assign values to variables
- Rect / Pol - convert from rectangular to polar and visa versa

Prime Factors |

To find Prime factors of any number do the following steps Prime factors can be found by using the FACT key. If we want the prime factors of 4200, we need to enter the number in our calculator and then factorise is. 4200 has four prime factors 2; 3; 5 and 7 |
