This calculator use the Reverse Polish notation (RPN) that is a mathematical notation wherein every operator follows all of its operands. Interpreters of Reverse Polish notation are often stack-based; that is, operands are pushed onto a stack, and when an operation is performed, its operands are popped from a stack and its result pushed back on. So the value of postfix expression is on the top of the stack. Stacks, and therefore RPN, have the advantage of being easy to implement and very fast.
