TI-84 Calculator Programming Guide

The TI-84 family includes TI-Basic, which can automate repeated calculations and classroom workflows. This page focuses on creating and running a simple program directly on the calculator.

Create a new program

  1. Press PRGM and move to NEW.
  2. Choose 1:Create New.
  3. Enter a short program name and press ENTER.

Quadratic formula example

The following TI-Basic example prompts for A, B and C and displays both roots when the discriminant produces real-number results in the current mode:

:Prompt A,B,C
:(-B+√(B²-4AC))/(2A)→X
:Disp "X1=",X
:(-B-√(B²-4AC))/(2A)→Y
:Disp "X2=",Y

Run the program from the PRGM EXEC menu. Test programs with values you already know before relying on them for new work.

Programs can change calculator state or stored variables. Save anything important before experimenting, and follow exam rules about stored programs.
