Formula Manipulation
Mathematica handles formulas of all types, from polynomials with millions of terms to complex combinations of higher mathematical functions. It provides powerful general transformation and simplification functions that automatically call on thousands of rules and algorithms—many original to Wolfram Research.
Simplify simplify, perhaps with assumptions about variables
FullSimplify apply full simplification procedures
FunctionExpand expand in terms of more elementary functions
    
Expand expand out algebraic expressions
Factor factor algebraic expressions
    
Reduce reduce out equations and inequalities
Series find a series approximation
