What Absolute Value Means

The absolute value of a number is its distance from zero, so it is never negative. Drop the minus sign if there is one.

|x| = x if x ≥ 0, and −x if x < 0   Distance between a and b = |a − b|

Worked Example

Tips

|a × b| = |a| × |b|, but |a + b| can be less than |a| + |b| (the triangle inequality).
