When working with a TI 83 calculator, finding the absolute value of a number can be done easily using a simple feature provided by the calculator. The absolute value of a number is its distance from zero on the number line, with no consideration for its sign. Here’s how you can find the absolute value of a number using a TI 83 calculator.
Step-by-Step Guide to Find Absolute Value on a TI 83
To find the absolute value of a number on a TI 83 calculator, follow these steps:
Step 1:
Enter the number whose absolute value you want to find.
Step 2:
Press the “MATH” button located towards the center left of the calculator keypad.
Step 3:
Use the right pointing arrow key to navigate to the “NUM” menu.
Step 4:
Scroll down until you find the “abs” function and press the corresponding number displayed on the screen, usually “1.”
Step 5:
After pressing the corresponding number, the calculator will display “abs(” on the screen.
Step 6:
Enter the number for which you want to find the absolute value, and close the absolute value function with a closing parenthesis “)”. For example, if you want to find the absolute value of -5, enter “-5)”.
Step 7:
Press the “ENTER” key to calculate the absolute value.
The calculator will display the absolute value of the entered number on the screen. It’s that simple!
