When I try to convert infix expression to postfix expression, 3*(3+6/2)

it will be converted to like this. 3362/+*

My problem is this, how can I handle if there is negative sign in front of parantheses? Like 3*-(3+6/2) or 3*(-(3+6/2))

When I try to convert these to postfix expressions, it would be like 3*362/+- and 3362/+-*, but none of these expressions are valid: I cannot calculate these expressions in common way which we use to calculate postfix expressions.

So is there any way to handle these?
