Editing Operand (section)

===Positioning of operands===
Depending on the [[mathematical notation]] being used the position of an operator in relation to its operand(s) may vary. In everyday usage [[infix notation]] is the most common,<ref name="Infix, Postfix and Prefix">{{cite web | url=http://www.cs.man.ac.uk/~pjj/cs212/fix.html | title=The Implementation and Power of Programming Languages | access-date=30 August 2014}}</ref> however other notations also exist, such as the [[prefix notation|prefix]] and [[postfix notation|postfix]] notations. These alternate notations are most common within [[computer science]].

Below is a comparison of three different notations — all represent an addition of the numbers '1' and '2'

:<math>1 + 2</math> (infix notation)

:<math>+\;1\;2</math> (prefix notation)

:<math>1\;2\;+</math> (postfix notation)
