Using each of the ten digits 0 to 9 exactly once, and using only the arithmetic operators: addition(+), subtraction(-), division(/), multiplication(*) and parentheses, generate an expression that equals 975.
Note:
Concatenation of two or more digits is permissible, so that, expressions like:
12*(4/3) + 56-78+9 = 3 are permissible.
However, utilization of exponentiation(^), factorial(!), or other mathematical expressions is not allowed.
For example, expressions like: 1834567^0 + 2! = 2 are not valid.
