How to Use a TI-84 Calculator on SAT, ACT, and AP Exams

Introduction

The TI-84 can be useful on calculator-permitted exam sections, but it should support your math skills instead of replacing them. Always check the official calculator policy for your specific test date.

Step-by-step preparation

1. Learn basic arithmetic, parentheses, exponents, and fractions.
2. Practice graphing functions from Y=.
3. Use tables to compare values quickly.
4. Review statistics workflows before test week.
5. Clear or reset settings only when your teacher or testing instructions require it.
6. Bring fresh batteries or charge your calculator if using a rechargeable model.

Practical example

For a quadratic question, graphing can help estimate roots and confirm your algebra. You should still know how to solve the problem by hand when exact answers are required.

Common mistakes

• Spending too much time searching calculator menus.
• Graphing with a bad window and trusting an empty screen.
• Forgetting exam calculator rules.
• Relying on calculator shortcuts without understanding the math.
