Mathematical Operations Allowed in Input File

Mathematical operations of addition(+), subtraction(-), and multiplication(*) are allowed in the input file line. Division(/) is not allowed since it can not be differentiated from the LCS end of line delimiter (/).

Parenthesis are NOT allowed. Operations are evaluated from left to right, with multiplication being performed, then addition/subtraction.
