Solución:

2/2 + (2-2)/2 = 1
2 - 22/22 = 1

2 + 2/2 - 2/2 = 2
2 + 2 + 2 - 2 - 2 = 2

2 + (2+2)/(2+2) = 3
2 + 22/22= 3

(2 + 2 + 2 + 2)/2 = 4
2 + 2/2 + 2/2 = 4

2 + 2 + 2 - 2/2 = 5
(2 + 2 + 2)/2 + 2 = 5

2 + 2*2 + 2 - 2 = 6
2 + 2 + 2 + 2 - 2 = 6

2 + 2 + 2 + 2/2 = 7

2*2*2 + 2 - 2 = 8

2*2*2 + 2/2 = 9

2 + 2 + 2 + 2 + 2=10
2*2 + 2*2 + 2 = 10

Y un poco más:

22 / 2 + 2 - 2 = 11
22 - 22/2 = 11

2*2*2 + 2 + 2 = 12
2^(2*2)- 2 - 2 =12

(2*2)! * 2/2 = 13

22 - 2 - 2 - 2 = 14

2^2^2 - 2 / 2 = 15

2^2^2 - 2 + 2 = 16

2^2^2 + 2 / 2 = 17

2^2^2 + 2 + 2 =18

22 - 2 -2/2 = 19

22 + 2 - 2 + 2 = 20
22/2*2 -2 = 20

22 - 2 + 2/2 = 21

22 + (2 -2)/2= 22

22 + 2 - 2/2 = 23

22/2 * 2 + 2 = 24
22 + 2 + 2 - 2 =24

22 + 2 + 2/2 = 25

22 + 2 + 2 + 2 = 28

22 + 2*2*2 = 30

22 + 22/22 = 33

22 + 2^(2*2)= 38
