A RPN calculator is a calculator that uses Reverse Polish Notation (RPN) as its input method. RPN is a way of expressing mathematical operations in which the operator follows the operands, rather than preceding them as in traditional infix notation.

For example, in traditional infix notation, the expression "2 + 3" would be written as "2 + 3 = 5." In RPN, the same expression would be written as "2 3 +," with the "+" symbol following the operands "2" and "3."

RPN calculators are often preferred by some users because they can be more efficient to use, as they do not require the use of parentheses or other symbols to indicate the order of operations. Instead, the order of operations is determined by the position of the operator in the RPN expression.

To use a RPN calculator, users typically enter numbers and operators in the order in which they want the calculations to be performed. The calculator will then evaluate the expression and display the result.

RPN calculators can be useful for a variety of purposes, including performing quick calculations, solving math problems, and analyzing data. They are often used in education, business, and other fields where mathematical analysis is important.(full-width)
