If 5 X 6 = 30 OR
6+6+6+6+6=30
Because 5 stands for the amount of sixes you add together so if 5 X 6 = 30 then 6 X 6 would just add six to the 5 X 6
6 X 6 = 36
5 X 6 = 30
36 - 30 = 6
Because all you did was add six.
you would take the answer 420 and split in half
first use 5 times 6 = 30 than add 6 times 1 = 6 so the product of 6 times 6 is 36

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).

Just add six.
first use 5*6=30 then add 6*1=6 the product of 6*6 is 36
15 is half again as much as 10, so the new product would similarly increase by 50%.
You double the product of 2x8.2x8 equals 16. 16 doubled which equal 16x2 equals 32.4x8 equals 32.
You could use it because it shows that its just 7 times 8 flipped!
first use 5 times 6 = 30 than add 6 times 1 = 6 so the product of 6 times 6 is 36
The second is half of the first.
You can add 50+6 and it equals 56
That's easy, just half it. 420 divided by 2 (5 is half of 10) which equals 210. (1) To check my answer, I did... 42 x5 (5 x 2=10 (carry the one), then 5 x 4=20 + 1= 120) ---- 210
It would seem more sensible to do the multiplication directly.
