# Algebraic Transformations

Mathematica includes functions for performing a variety of specific algebraic transformations. Some are algorithmically straightforward; others include highly sophisticated algorithms, many developed and refined at Wolfram Research.

## ReferenceReference

### General Operations

Simplify apply transformations to try to simplify an expression

FullSimplify apply a full set of simplification transformations

FunctionExpand attempt to expand in terms of more elementary functions
