What is PEMDAS?
PEMDAS/BODMAS fixes the order operations are evaluated in: parentheses, exponents, multiplication and division, then addition and subtraction.
How it works
A safe recursive-descent parser (no eval) reduces parentheses from the inside out, then applies operators by precedence, printing the expression after each operation.
