Example 3

easy
Evaluate (−12)−(−5)+3(-12) - (-5) + 3.

Solution

  1. 1
    Rewrite subtraction as addition: (−12)+5+3(-12) + 5 + 3.
  2. 2
    Combine: 5+3=85 + 3 = 8, then −12+8=−4-12 + 8 = -4.

Answer

−4-4
Subtracting a negative is the same as adding the positive. Rewriting all subtractions as additions of the opposite simplifies integer arithmetic.
