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
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.
If you say (9-8+5) times 4 you get 24. Hope I could help.

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).
8 times 4 times 8 times 4 equals 1024.
