Step 1: Rewrite as an addition problem -5\goldD {- (-6)}=-5\goldD {+6} −5−(−6) = −5 +6 Step 2: Start at the first number in the addition problem, in this case -5 −5. 7 (mathematics) the symbol ∓, meaning "minus or plus", used alongside the plus-minus sign to show that a negative value is to be taken where the positive value is indicated by the plus-minus sign, and vice versa (as in (x ± 1) / (x ∓ 2), which means (x + 1) / (x - 2) and (x - 1) / (x + 2).

The ∓ always has the opposite sign to ±. 11
