NOTE: This tutorial only covers TI-83 syntax and the syntax it shares with TI-84. This tutorial covers the basic tools needed to create any basic program. Calculator programs are useful for math programs, since they have many more math commands than a typical computer. The main limitations are the memory and processor restrictions, along with the low screen resolution. The first step is to access the program menu. Press the key labeled "PRGM" in the upper middle part of the keypad. If your calculator is new, you should not have any programs in this menu. Let's fix that!
