To find 8 X 7 you can simply double 4 X 7. The answer being 56.
This is true becasue of the associative property of multiplication which states any order of number being multiplied together will give you the same answer.
2 X 4 X 7 = 8 X 7 = 56
7 X 4 X 2 = 28 X 2 = 56 + we know are math facts!
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).
you can muit by 4s and 8s.
324 = 3 x 108 324 x 4 = 3 x 108 x 4
324 x 4 = 1,296
A square number is the product of a number and itself. 16 is square; it is the product of 4 and 4; 4 times 4.
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).
you can muit by 4s and 8s.
double 4 times 4
It would seem more sensible to do the multiplication directly.
Multiply.
324 = 3 x 108 324 x 4 = 3 x 108 x 4
508*4=2032
You can do 4 rows and 13 columns and you get 52. product = sizeof (char [4][13]); of course it is just a joke, in actual code you write product = 4*13;
Multiply them: 26*4 = 104
324 x 4 = 1,296
You double the product of 2x8.2x8 equals 16. 16 doubled which equal 16x2 equals 32.4x8 equals 32.
