How to do the absolute value on a TI-84?

Calculating absolute values on a TI-84 calculator is a simple process that can be done in a few easy steps. Follow these instructions to find the absolute value of any number on your TI-84 calculator:

1. Turn on your TI-84 calculator by pressing the “ON” button.
2. Enter the number for which you want to find the absolute value.
3. Press the “2nd” button, which is located in the top left corner of the keypad.
4. After pressing the “2nd” button, press the “0” button to access the “MATH” menu.
5. Scroll down using the arrow keys until you find the “abs” function. The “abs” function stands for absolute value.
6. Press the number key corresponding to the “abs” function or scroll to highlight it and then press “ENTER.”
7. Your calculator screen will display “abs(” followed by the number you entered. Press “ENTER” again to calculate the absolute value.
8. The absolute value of the number will be displayed on the screen.

That’s it! You have successfully calculated the absolute value of a number on your TI-84 calculator.
