Expressions that contain parenthesis, such as '(1+2)*3', are evaluated by noting the precedence order and entering the form as '1 2 + 3 *'. For example, to evaluate the expression '1 + 2' in RPN, the user is required to enter '1 2 +' and the expression is evaluated immediately after the operator. RPN Mode RPN, which stands for Reverse Polish notation, is a stack-based notation where operators are designed to follow their operands. Expressions entered in algebraic input mode are done in a manner that closely resembles the natural form of the expression and the order of the operations is determined by operator precedence and parenthesis. The calculator mode is set by clicking on the 'ALG/RPN' symbol in the status bar or by changing the mode inside the menu dialog box.Īlgebraic input mode is commonly referred to as 'infix notation' and is widely used by most handheld calculators.
