Sign of Operation

You are given two integers $a$ and $b$. Insert one of the operators +, -, or * between them so that the value of the resulting expression is as large as possible. If that largest value can be reached by more than one operator, print NIE instead.

A single line contains two integers $a$ and $b$ ($-10^4 \le a, b \le 10^4$).

Print the expression that yields the largest value, in the form a<operator>b=result, on one line. Wrap a negative operand in parentheses (for example (-5)). Do not put the result in parentheses. If more than one operator produces the largest value, print NIE instead.
