Do two plus signs make a minus?
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
