22=4!-sqrt(4)+(4-4)

23=4!-4^(4-4)

Alternative suggestion: 28 = (4+4)*4-4
29 = 4!+4/4+4

126 = 256/2-2

30 = 4!+sqrt(4)+sqrt(4)+sqrt(4)

31 =/= 4!*sqrt(4)......+(4/4)
Hmm... can't get (30 + 1) or (32 - 1), but need to make uneven number.

This is fun, but I am in the mood for more of a challenge. Shall we try a more difficult problem, how about the five fives problem?

We should construct all the numbers from 4 to 50 using five fives.

Nice, Rudin. I didn't think of that.

Yes, very fun.
Alright, let's try.

Components
4=5-5/5
1=5/5
2=(5+5)/5
5!=120
5^5=3125
3=(5+5+5)/5

5=5*((5/5)*(5/5))

4*4*4+4=68
