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
63
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).
40
you would take the answer 420 and split in half
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
You can use the product of 5x6, which is 30, to find the product of 6x6 by recognizing that 6x6 can be expressed as 6x(5+1). This means you can calculate 6x5 to get 30, and then add another 6 to that result. Therefore, 6x6 equals 30 + 6, which gives you 36.
You can use the fact that 4 times 2 equals 8 to help find 7 times 8. Since 7 times 4 equals 28, you can double that product to find 7 times 8. So, 7 times 8 is 28 doubled, which equals 56. Therefore, 7 times 8 is 56.
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
