I think I got this for the first one .. 3 + 4 = 28 Well ... 3 + 4 = 7 and 7 x 4 = 28 Now let's see if it works for the second one .. 7 + 3 = 40 7 + 3 = 10 and to get 40 it's x 4 again Let's try the third one .. 9 + 5 = 56 9 + 5 = 14 and YES it's x4 again So the last one is .. 12 + 5 = 17 and 17 x 4 = 68 !!
I think I got this for the first one ..
3 + 4 = 28
Well ... 3 + 4 = 7 and 7 x 4 = 28
Now let's see if it works for the second one ..
7 + 3 = 40
7 + 3 = 10 and to get 40 it's x 4 again
Let's try the third one ..
9 + 5 = 56
9 + 5 = 14 and YES it's x4 again
So the last one is ..
12 + 5 = 17 and 17 x 4 = 68 !!
68
