You would use this calculator to find an absolute value of a real number. To use this calculator, enter the value for $x$ in the operand field provided below, An Absolute Value means only how far a number is from zero, and is calculated by removing any negative sign in front of a number, and to think of all numbers as positive (or zero). We put "|" marks either side of a number (they are called "bars"), a number inside these bars e.g. $| -1 | = 1$ represent an Absolute value. While we use bars (|), sometimes, however, absolute value can also be written as "abs()", so $abs(−1) = 1$
