Four Fours

December 6th, 2006 · 3 Comments

I just found out about a little math game called Four Fours. Basically what you try to do is try to represent integers using only the number 4 and a few common mathematical operators, for example:

0 = 4 – 4 + 4 – 4
1 = ( 4 + 4 ) / ( 4 + 4 )
2 = ( 4 * 4 ) / ( 4 + 4 )

There are also solvers out there in C# and also in Python.
