A couple of years ago I posted the problem of four fours.
Recently I stumbled upon Gene Wirchenko’s Blog, and he had s similar problem.
Here is a variation of his problem. Combine 2, 3 and 5 to make all the numbers 0-22. Use each of the three digit exactly once, but you are free to use addition, multiplication, division, subtraction, brackets, exponentiation and factorial as often as you like.
For those of you who are not familiar with factorials a short reminder:
0! = 1
1! = 1
2! = 2*1
3! = 3*2*1
4! = 4*3*2*1
etc.
