You may be tempted to use the calculator for this problem, but the solution is much easier and much quicker without it. When a negative number is subtracted from another quantity, the two negatives make a positive, so that the net result is addition. Therefore, 2 − (−3) = 2 + 3 = 5 and 3 −(−2) = 3 + 2 = 5. You can thus divide both quantities by 5 to arrive at the simplified comparison below:
−2 + 3 = 1 −3 + 2 = −1
Therefore, Quantity A is greater.
