-9 x -8 = +72
NOTE:
When multiplying like signs, the product is positive.
Examples:
+2 x +3 = +6
-4 x -5 = + 20
When multiplying unlike signs, the product is negative.
Examples:
-2 x +3 = -6
+4 x -2 = -8
If x = 8, then 23 -x - 9 = 23 - 8 - 9 = 6
9 x 28 = (9 x 20) + (9 x 8) 9 x 20 = 180 9 x 8 = 72 180 + 72 = 252 9 x 28 = 252
If: 8+x = 17 Then: x = 9
8 x (9 - 3) 4^2 (9 - 3) - 4^2 12-4^2 4 x 8 =32
(8 - x) / 6 = 98 - x = 54x = 8 - 54x = -46OR8 - (x/6) = 98 = x/6 + 9x/6 = 8 - 9 = 1x = 6
