Answerit's not 20, because 20 is the sum, and difference is subtraction, and product is multiplication.
-8
20 x 8 = 160
28
S = -12, p = -160
(12 * 8) - (12 + 8) = 96 - 20 = 76
The numbers are 8 and 20

The sum of 20 and -4 is +16, while the product of 4 and -2 is -8. The answer to the question is therefore -2.
The partial products are 40*20 + 40*8 + 20*2 + 2*8 = 800 + 320 + 40 + 16 = 1176.
