5 + (2 x 7) - (18/5) = 15.4
18 + 12 + 0 - 4 - 10 = 16

-18 + 25 = 7
x3+3x2-22x-90 divided by x-5 equals x2+8x+18 For the answer to be correct then the quotient multiplied by the divisor must be equal to the dividend. Hence:- (x-5)*(x2+8x+18) Multiplying out the brackets term by term: x3-5x2+8x2-40x+18x-90 Collecting like terms in descending order: x3+3x2-22x-90 So the answer is correct.
1 / 2 * 18 - 5 = 9 - 5 = 4

-18
(18/3) + 6 -(2 x 4) = 4
There is no need to simplify this, it is only a sum. 21 + (10/2) - 18 = 8
18 + 12 + 0 - 4 - 10 = 16

9 + 2 + 30 - 5 + 18 - 19 = -1
-18 + 25 = 7
