31, if the question is (5 + 6) x (3 - 2), 21, if the question is 5 + 6 x 3 - 2.
4 + -5/2 - 5 = -7/2 = -3 and 1/2

4 + -5/2 - 5 = -7/2 = -3 and 1/2
2 minus 2/5 plus 1/2 minus 4 = -1.9

2 - 5 + 3 - 5 = -5
4 - 5 + (-2) = -3
Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.
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
(((50 / 2) - 5) * 4) + 1 = 81order of operations:(50 / 2) - (5 * 4) + 1 = 6
