Finding the maximum (Posted on 2004-04-21) Difficulty: 3 of 5
Using only standard math operators (+, -, *, /) and functions (absolute value, square root, powers, and so on), give a function that calculates MAX(A,B,C).

Alternate version, for programmers only: using any language (BASIC, C, Excel, whatever) find the maximum of A, B, and C, but be careful when writing the program, because you cannot use the "" key, for it's broken (thus writing things like IF A>B is impossible...) and you cannot use the "M" key either, for it's also broken (...and writing H=MAX(A,B) is also not possible.)
