Example 1

easy
Evaluate ∣−7∣+∣3∣|{-7}| + |3|.

Solution

  1. 1
    The absolute value of −7-7 is the distance from 0: ∣−7∣=7|{-7}| = 7.
  2. 2
    The absolute value of 33 is ∣3∣=3|3| = 3.
  3. 3
    Add: 7+3=107 + 3 = 10.

Answer

Absolute value measures distance from zero on the number line and is always non-negative. For any number aa, ∣a∣=a|a| = a if a≥0a \ge 0 and ∣a∣=−a|a| = -a if a<0a < 0.
