5 5 5 5=24
9 3 3 8=24
8 3 3 9=24
3 8 3 9=24

Answer 1

1.9-9+(9-9)/9 = 0
2.(9+9)/9+9-9 = 2
3.(9+9+9+9)/9 = 4
4.(9*9-9-9)/9 = 7
5.9+9-9-9+9 = 9
6.(9*9+9)/9-9 =1
7.(9+9)/9+9/9 = 3
8.9-(9+9+9)/9 = 6
9.9-9+9-9/9 = 8
10.9/9+9+9-9 = 10
11.3+5+2*8 = 24
12.(9+10-11)*3 = 24
13.11+8+7-2 = 24
14.5*5-5/5 = 24
15.(9-3-3)*8 = 24
16.(8+3)*3-9 = 24
17.(3+8)*3 - 9 = 24
