double 8
8 x 2 = 16 (8 x 2) double 16
16 x 2 = 32 (8 x 4) double 32
32 x 2 = 64 (8 x 8)
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).
first use 5 times 6 = 30 than add 6 times 1 = 6 so the product of 6 times 6 is 36
You can use 4x7 to find 8x7 because 4 x 2 is 8, and you are simply doubling one of the numbers you are multiplying, (4 to 8) and so multiply your answer from 4x7 by 2 to get the answer to 8x7. 4x7 is 28 and 8x7 is 56, and 28 x 2 is 56.

Doubling a number is equivalent to multiplying by 2. Doubling twice (doubling, and then doubling the result again) is equivalent to multiplying by 4. (Also, doubling three times is the same as multiplying by 8, doubling 4 times is the same as multiplying by 16, etc.)
You cannot since there is no product of a single number!

since 4 is 2 times 2 just double 7 twice: 7 doubled = 14 and then 14 double = 28
it would be 36 times two
first use 5 times 6 = 30 than add 6 times 1 = 6 so the product of 6 times 6 is 36
you can do 5 12 times

Yes, if you add 6 four more times to the product you got with 6 times 3.
double 4 times 4
