Using the numbers 4, 4, 4 , 4 only once and you must use all 4 numbers in every solution and using only addition, subtraction, multiplication and division make the numbers through 1-20.

Example for the number 1:
((4/4)/4)*4 = 1

See I used all four 4s and got the number one.

That's still 1

let me cheat and jump to 5
((4*4)+4)/4=5

edit 2: ((4*4)-4)/4=3
edit 3: ((4*4)/(4+4)=2

no no adam.

ill help with 2 its just: (4/4)+(4/4)

(4*4)+4-4 = 16
(4*4)-4-4 = 8
((4-4)*4)+4 = 4

i know, but i always figure out the more complicated methods before i see the simple ones lol.
4+4+4-4=12
((4*4)/4)+4=8
((4+4)/4)+4=6
4/4+4+4=9
so wee have:
1
2
3
4
5
6
8
9
12
16

(4*4)+(4/4) = 17
(4*4)-(4/4) = 15

(4+4)-(4/4) = 7
Is that right lol.
