11.  The absolute value of a number is its distance away from zero. ◦ Absolute values are always non-negative ◦ |x| = x if x≥0 ◦ |x| = -x if x<0  Evaluating absolute value expressions 1.Substitute values in first 2.Simplify inside the absolute value 3.Take the absolute value 4.Simplify further, if needed
