Is this a homework assignment? (Homework and coursework questions can only be posted in

I have no idea what you are trying to do. Arithmetic operators (except unary minus) work on two operands. Therefore, a arithmetic formula has one more operand than there are operators. But, your example has 3 operands and 3 operators.
Are you saying that you want each number to have a trailing + or - sign to indicate whether the number is positive or negative and you then want to add up all of the signed numbers?
Are you only processing single-digit numbers?
