Here are ten simple tips and tricks to help you get the most out of your TI-84 calculator.
1. Know Your Shortcuts
Many users don’t realize that the TI-84 has shortcuts for common operations. For example, pressing 2nd and MODE quickly clears the home screen without deleting your data. Learning shortcuts can make your workflow much faster.
2. Customize the Mode Settings
Before starting any calculations, check the mode settings. For graphing problems, ensure the angle is in degrees or radians as needed. Switching between float and scientific notation can also help in getting precise results.
3. Use the Memory Wisely
Your TI-84 has memory for storing values and programs. Use the STO> button to store numbers for quick recall. This is especially helpful when solving long problems or working with multiple equations.
4. Graph Efficiently
When graphing functions, always set the window properly. Use ZOOM and TRACE features to see important points on your graph clearly. This can save you from guessing values or misreading the graph.

The CATALOG button contains all the functions on your calculator. If you forget a command, the catalog is a quick way to find it without flipping through the manual. It’s a time saver once you get used to navigating it.
8. Use Parentheses Correctly
Many mistakes happen because of missing or misplaced parentheses. Always check your expressions carefully, especially when combining multiple operations. Correct use of parentheses ensures your answers are accurate.
9. Master Fraction and Decimal Conversions
Switching between fractions and decimals can be tricky. Use the MATH button and select Frac to convert decimals to fractions easily. This tip is helpful for simplifying answers and presenting them in the preferred format.
