, also known as prefix notation, is a form of notation for logic, arithmetic, and algebra. Its distinguishing feature is that it places operators to the left of their operands. In simple word, if you are prefixing the operator to the number, it is called Polish notation.
ex Polish notation: +22
Reverse Polish notation (or RPN)
is a mathematical notation wherein every operator follows all of its operands, in contrast to Polish notation, which puts the operator in the prefix position. In simple word, if you suffixing the operator to the number, it is called Reverse Polish notation.
ex Reverse Polish notation: 22+
