In a [[programming language]], an '''expression''' is an entity which combines a number of data item with [[operator]]s to produce a value which is then used in some way - perhaps saved in [[main memory]] or a [[Central Processing Unit|CPU]] [[register]] for use later in the [[program]].

An example of an expression would be ''((A * 3) + b)''.
