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