Absolute value is a mathematical operation that yields the distance of a number from zero on the number line, disregarding its sign. On a graphing calculator, finding the absolute value is a straightforward process that can be achieved with a few simple steps.
Formula: The absolute value of a number ‘a’ is denoted as |a| and is calculated by ignoring the sign of the number.
How to Use:
- Enter a numerical value into the designated input field.
- Click the “Calculate” button to find the absolute value.
- The result will be displayed below the input field.
Example: Suppose you want to find the absolute value of -5. Enter -5 into the input field and click “Calculate.” The result will be displayed as “The absolute value is: 5.”
