Tree traversal: Infix (In-order) is also a tree traversal order. It is described in a more detailed manner on this page. Calculator input methods: comparison of notations as used by pocket calculators; Postfix notation, also called Reverse Polish notation; Prefix notation, also called Polish notation
In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation.It can produce either a postfix notation string, also known as reverse Polish notation (RPN), or an abstract syntax tree (AST). [1]
Video: Keys pressed for calculating eight times six on a HP-32SII (employing RPN) from 1991. Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands.
To study how exactly the infix notation and postfix notation differ we used one of the very old HP calculators. I was wondering that when you worked for HP did you help develop some postfix calculators? Do you prefer infix notation or postfix?". Letters-General Questions Answered. woz.org.

Order of operations arose due to the adaptation of infix notation in standard mathematical notation, which can be notationally ambiguous without such conventions, as opposed to postfix notation or prefix notation, which do not need orders of operations.
Polish notation (PN), also known as normal Polish notation (NPN), [1] Łukasiewicz 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, as well as reverse Polish notation (RPN), in which operators follow ...

An infix is an affix inserted inside a word stem (an existing word or the core of a family of words). It contrasts with adfix , a rare term for an affix attached to the outside of a stem, such as a prefix or suffix .
