Hey xeon123.

Typically we write the expression as y = max(x1,x2,x3,...) in notational terms.

One way to write this is to use Heaviside functions where H(x) = 0 for x < 0 and 1 otherwise. If you want to just use a computer though then you can either sort a list and get the last element or implement an optimized routine that does the minimal number of compares to get the answer.
