 Numbers - Absolute Value - Contents

The absolute value of a real number is the positive value of the number. If it is a negative number, then the negative sign is removed. Multiplying the negative number by negative one performs this math operation. If the number is positive, then it remains a positive number. If the number is zero, then it remains zero. Measurements use the absolute value because a length is always positive. The absolute value can also mathematically define a set of answers to a function. For instance, taking the square root of a number that is first squared results in the absolute value of the number, because the results are always the positive value.
