I am not at all sure how it will help you find 13 times 8!
8
Since 8 is 2 x 4, 9 x 8 is 2 x 9 x 4
9 time 4 = 36 9 times 8 =72 36+36=72 half of 72 is 36 half of 8 is 4
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.
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 (7 \times 8) using (4 \times 8), you can break down (7) into (4 + 3). First, calculate (4 \times 8), which equals (32). Then, calculate (3 \times 8) (which can also be done as (4 \times 8 - 4 \times 8 + 3 \times 8)), resulting in (24). Finally, add the two results: (32 + 24 = 56), so (7 \times 8 = 56).
4+4
6 is 1.5 times 4. 48 is 1.5 times 32.
Don't know how you find it but I guess the answer is -2. -2 x -2 =4 4 X -2 = -8
4 is 8 times smaller than 32. You can find this simply by dividing 32 by 4, which would give you 8. You can also check your answer by multiplying 4 and 8 to make sure it results in 32, because 32 it 8 times greater than 4 (and 4 times greater than 8).
To find (3 \times 8) using 2s and 1s facts, you can break it down into simpler components. First, recognize that (8) can be expressed as (4 + 4), so (3 \times 8) can be rewritten as (3 \times (4 + 4)). This gives you (3 \times 4 + 3 \times 4). Since (3 \times 4 = 12), you can add (12 + 12) to get (24). Thus, (3 \times 8 = 24).
8 times 4 times 8 times 4 equals 1024.
