Erm, well.
You want 8 which is 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1.
And four 2s are 2 x 4 and 2 x 4 = 8 because 2 groups of four is like 4 + 4 and that makes 8 so yeah.

Oh, what a happy little question! To get 9 using four twos, you can simply add them together like this: 2 + 2 + 2 + 2 + 2 = 10. Then, take one of those twos away to make it 10 - 2 = 8. Finally, add the last two you took away to get 8 + 2 = 9. There you go, a beautiful little math problem solved!
64 twos go into 128.This is not hard to do. If you look at the first two figures - 12 - and ask how many twos in 12 the answer is 6 (6x2=12). Then look at the last figure - 8 - and ask how many twos in eight, the answer is 4 (2x4=8). The answer is 64.
22 ÷ 2 - 2 = 9
4!-(4/4+4)=19
