Go to content How to write a simple program to add two numbers together on a GDC (graphical display calculator). This explanation uses the TI-82/83/84 calculators.

1. Press PRGM to select the program entry menu.
2. Select NEW, enter the name "ADD" and begin entering the program line by line.
3. Once the program is completed, quit then select PRGM again and the program name "ADD".

You will be prompted for the values of A and B, then the sum will be displayed. You can get a better display of the maths by downloading special TeX fonts from jsMath. In the meantime, we will do the best we can with the fonts you have, but it may not be pretty and some equations may not be rendered correctly.
