Using only math symbols (no functions like sin, cos, log, etc.) create an expression with only two 2s equal to 5 (no other digits or constants).

Usually function would mean functions with one argument. The plus operation takes on two arguments.

Of course, you need some "one argument functions", so we would have to decide which were the most simple functions. This is something that's probably best done in the problem.

I think of "rounding down" as a function but it's probably just a manner of opinion on a lot of them. Unless you could find something that turned 2 into 1, (2/2)/.2 would be closest solution in this situation
