What is true about the absolute value of a number and the absolute value of its opposite?

Average Rating

 Sep 07, 2011 Rating Absolute Values by: Karin The absolute value of a number is it's distance from zero on a number line. Therefore, the absolute value of a number is always positive. The absolute value of a number and the absolute value of it's opposite are always the same. For example, the absolute value of 5 is 5, written as: |5| = 5 The absolute value of -5 is also 5, written as: |-5| = 5 Why are they the same? The number 5 is 5 units away from 0 on the number line. -5 is also 5 units away from zero on the number line. It doesn't matter what direction on the number line, so the absolute value is always positive. I hope this helps, Karin
