Polish Equation Title For Free

Polish notation (PN), also known as normal Polish notation (NPN), ?ukasiewicz notation, Warsaw notation, Polish prefix notation or simply prefix notation, is a mathematical notation in which operators precede their operands, in contrast to the more common infix notation, in which operators are placed between operands, ...

Reverse Polish notation, also known as postfix notation, contrasts with the "infix notation" of standard arithmetic expressions in which the operator symbol appears between the operands. In practice RPN can be conveniently evaluated using a stack structure.

Polish notation was invented in 1924 by Jan Lukasiewicz, a Polish logician and philosopher, in order to simplify sentential logic. The idea is simply to have a parenthesis-free notation that makes each equation shorter and easier to parse in terms of defining the evaluation priority of the operators.

In reverse Polish notation, the operators follow their operands. For example, to add 3 and 4 together, the expression is 3 4 + rather than 3 + 4. The expression 3 ? 4 + 5 in conventional notation is 3 4 ? 5 + in reverse Polish notation: 4 is first subtracted from 3, then 5 is added to it.

In mathematics and computer science, Polish notation is a way of expressing arithmetic or algebraic formulae which is unambiguous without the use of parentheses.

Prefix notation is also known as polish notation. In this notation, the operators are written before the operands, not like the infix in which the operators are in-between the operands. For example, the infix notation (5+6)*7 will be written as *+567 in prefix notation.
