Common misconception

Keywords

• Additive inverse - The additive inverse of a number is a number that, when added to the original number, gives the sum of 0.

• Absolute value - The absolute value of a number is its distance from zero. E.g. 5 and (−5) are both 5 away from zero and so both have an absolute value of 5
