In this article, we’ll provide a step-by-step guide on how to write programs for the TI-84 Plus on a computer.
Getting Started
Before you begin writing programs for your TI-84 Plus, you’ll need to have a computer with a compatible operating system (such as Windows or macOS) and a TI-84 Plus calculator. You can purchase a TI-84 Plus calculator online or at a local electronics store.
Understanding the TI-84 Plus Calculator
Before you start writing programs, it’s essential to understand the basics of the TI-84 Plus calculator. Here are some key features to keep in mind:
- Graphing capabilities: The TI-84 Plus has a built-in graphing function that allows you to create custom graphs and charts.
- Programming language: The TI-84 Plus uses a programming language called BASIC (Basic Instruction Set for Computing).
- Memory: The TI-84 Plus has a limited amount of memory, which means you’ll need to write programs that don’t require too much memory.
- Input/output: The TI-84 Plus has a built-in input/output system that allows you to read and write data to the calculator.
Writing Programs for the TI-84 Plus
Writing programs for the TI-84 Plus is a relatively straightforward process. Here’s a step-by-step guide to get you started:
- Choose a programming language: The TI-84 Plus supports BASIC, but you can also use other programming languages such as Pascal or C.
- Write your program: Start by writing your program in the chosen programming language. You can use a text editor or a programming IDE (Integrated Development Environment) to write your program.
- Use the TI-84 Plus calculator’s built-in functions: The TI-84 Plus has a wide range of built-in functions that you can use to perform calculations, graph data, and more.
- Use external libraries: You can also use external libraries to access additional functions and features.

Writing a Simple Program
Let’s take a simple example and write a program that calculates the area of a rectangle. Here’s a step-by-step guide:
- Choose a programming language: We’ll use BASIC to write our program.
- Write your program: Start by writing your program in BASIC:
10 PRINT "Enter the length and width of the rectangle: "
20 INPUT "Length: ", L
30 INPUT "Width: ", W
40 PRINT "The area of the rectangle is: ", L * W - Use the TI-84 Plus calculator’s built-in functions: We’ll use the
PRINTfunction to display the result, and theINPUTfunction to get user input. - Use external libraries: We can use the
PRINTfunction to display the result, and theINPUTfunction to get user input.

| Function | Description |
|---|---|
| Display text or data | |
| INPUT | Get user input |
| L | Length |
| W | Width |
| * | Multiply two numbers |
Writing a More Complex Program
Let’s take a more complex example and write a program that calculates the area of a triangle. Here’s a step-by-step guide:
- Choose a programming language: We’ll use BASIC to write our program.
- Write your program: Start by writing your program in BASIC:
10 PRINT "Enter the base and height of the triangle: "
20 INPUT "Base: ", B
30 INPUT "Height: ", H
40 PRINT "The area of the triangle is: ", 0.5 * B * H - Use the TI-84 Plus calculator’s built-in functions: We’ll use the
PRINTfunction to display the result, and theINPUTfunction to get user input. - Use external libraries: We can use the
PRINTfunction to display the result, and theINPUTfunction to get user input.
