1+8x7=57 but (1+8)x7=63. I'm not sure what you're looking for.
if you want to be specific, the equation should look like this:\ (10x10) + (8x7) so... 100 + 56 equals 156! try it in a calculator
gcf(16x8, 24x7) = 8x7 16x8 = 8x7 x 2x 24x7 = 8x7 x 3
or by: magickaela 8x7= 56 56-6
8 x 7 = 56
You can use the product from 4x7 to find the product of 8x7 by doubling the answer to 4x7. The product of 4x7 is 28 and the product of 8x7 is 56 (28 doubled is also 56).
