Stinky Sally was sitting all by her lonesome one day and thought about something silly. "How can I use exactly four 4's and the operations +, -, *, and / to make equations that equal 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Then she painted her nails green and colored her hair bright red.

0 = 4 + 4 - 4 - 4
1 = 4 - 4 + 4/4
2 = 4/4 + 4/4
3 = (4 + 4 + 4)/4
4 = ((4 - 4)/4) + 4
5 = (4 + (4*4))/4
6 = ((4 + 4)/4) + 4
7 = 4 + 4 - (4/4)
8 = (4 + 4)*(4/4)
9 = 4 + 4 + (4/4)

4+4-4-4=0
4*4/4/4=1
(4/4)+(4/4)=2
(4+4+4)/4=3
(4+4*4)/4=5
(4+4)/4+4=6
4+4+4-4=8
(4/4)+4+4=9
hmmm can't do 4 and 7 yet...
