First , please have a look at this :
http://www.carljohansen.co.uk/fourfours/ or google for the terms "four
fours"
I do not know C sharp ,so that i cant read the solution in that page , but
my idea is that I will subtitude every operator + - * / until I get the
result in a recursive way , but it will take a long time and CPU usage

Do you know any solution for this in the most rubish way

Thanks
