Just add six.
first use 5*6=30 then add 6*1=6 the product of 6*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 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
To find the product of 324 and 4 using the product of 108 and 4, you can first recognize that 324 is three times 108 (since 324 = 3 × 108). Therefore, you can calculate 108 × 4 to get 432, and then multiply that result by 3. This means 324 × 4 = 3 × (108 × 4) = 3 × 432, which equals 1296.
you would take the answer 420 and split in half
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.
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.
To find the product of 324 and 4 using the product of 108 and 4, you can first recognize that 324 is three times 108 (since 324 = 3 × 108). Therefore, you can calculate 108 × 4 to get 432, and then multiply that result by 3. This means 324 × 4 = 3 × (108 × 4) = 3 × 432, which equals 1296.
