You can use 2*8 to find 4*8 by solving 2*8, then multiplying it by 2. This is equivalent to 4*8, or 32.
To find (4 \times 12), you can break it down using the 10s and 2s facts. First, recognize that (12) can be expressed as (10 + 2). Then, use the distributive property: (4 \times 12 = 4 \times (10 + 2) = (4 \times 10) + (4 \times 2)). This gives you (40 + 8 = 48), so (4 \times 12 = 48).
You can use the fact that 4 is equal to 2 times 2 and the fact that 9 can be expressed as 3 times 3. By multiplying these facts, you can calculate 4 times 9 as follows: 4 times 9 equals (2 times 2) times (3 times 3). This can be rearranged to (2 times 3) times (2 times 3), which simplifies to 6 times 6, giving you 36 as the answer.
since 4 is 2 times 2 just double 7 twice: 7 doubled = 14 and then 14 double = 28
To find the perimeter, find 2 times the length and add 2 times the width. 2(3) + 2(4) = ? 6 + 8 = 14 inches
4 times 7 = 28 2( 4 times 7 ) = 2 times 28 = 56. I hoped I helped. XOXO W T F you don't know :(

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.

I know my 22 times table so it is 88.For those who did not advance beyond the 12 times tables at school, the easiest method probably is22 * 4 = (11 * 2) * 4 = 11 * (2 * 4) = 11 * 8 = 88 .
2 x 4 = 8
Don't know how you find it but I guess the answer is -2. -2 x -2 =4 4 X -2 = -8
double 4 times 4
To calculate (6! \times 2! \times 4! \times 3!), we first find the factorials: (6! = 720) (2! = 2) (4! = 24) (3! = 6) Now, multiplying these together: (720 \times 2 \times 24 \times 6 = 207360). Thus, (6! \times 2! \times 4! \times 3! = 207360).
To find 4 times 7, you can double the multiplication fact of 2 times 7. Since 2 times 7 equals 14, doubling that gives you 4 times 7, which also equals 28. Thus, 4 times 7 can be derived from doubling 2 times 7.
