I was wondering how you would seperate operands in a multiple-digit Prefix notation expression.
For example, how do you know if

+12344

means 123 + 44 or 12 + 344? What i am asking is how do you know when one operand ends and another begins?

You could use parenthesis to remove the ambiguity.

Could you use whitespace?

If the user inputs it in a certain order that would also remove any ambiguity.
