Answer provided by our tutors
1. Ignore the signs and find the difference.
2. Give the answer the sign of the larger number.
EXAMPLE 1: (-5) + 7 = _____
To find the difference, take the larger number minus the smaller number. 7 – 5 = 2. Looking back at the original problem, the larger number, 7, is positive, so the answer is positive: (-5) + 7 = 2.
