5+3=8x4=32-8=24+2=26x7=182
If order of operation is followed then the mutiplication has to be done first.
Then you add/subract the rest of the numbers from left to right.
5 + 3 x 4 - 8 + 2 x 7 = X
(3x4) (2x7)
5 + 12 - 8 + 14 = X
X=23
Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.

31, if the question is (5 + 6) x (3 - 2), 21, if the question is 5 + 6 x 3 - 2.
3 + 6 - 2 + 14 - 3 + 2 = 20

3 + 3 - 7 + 2 - 1 + 109 = 109
(x - 1)(x + 3) Think of 2 numbers which added together give +2 and which multiplied together give -3
7-4+3x0+1=7
(x-2)*(2x2+5x-3) Multiply out the brackets term by term taking care with the minus terms:- 2x3-4x2+5x2-10x-3x+6 Collect like terms:- Answer: 2x3+x2-13x+6
3 plus 2 is 5
Because adding a negative is the same as subtracting a positive. In other words, minus a plus is he same as plus a minus. For example 5+ (-3) = 5-3 = +2 5 -(+3) = 5-3 = +2 Remember minus a plus = = minus plus a minus = minus plus a plus = plus minus a minus = plus
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
