"Values for Symbols" discussed how you can use transformation rules of the form x->value to replace symbols by values. The notion of transformation rules in Mathematica is, ...

AlgebraicIntegerQ[a] yields True if a is an algebraic integer, and yields False otherwise.

When working in Mathematica , you will often find it useful to view groups of functions that relate to a specific subject area or set of tasks. The Documentation Center ...

Mathematica provides representation of algebraic numbers as Root objects. A Root object contains the minimal polynomial of the algebraic number and the root number—an integer ...

"Defining Functions" discusses how you can define functions in Mathematica. In a typical case, you would type in f[x_]=x^2 to define a function f. (Actually, the definitions ...

These "How tos" give step-by-step instructions for common tasks related to algebraic computation in Mathematica .

 

Polynomial algorithms are at the core of classical "computer algebra". Incorporating methods that span from antiquity to the latest cutting-edge research at Wolfram Research, ...

TransformationFunctions is an option for Simplify and FullSimplify which gives the list of functions to apply to try to transform parts of an expression.
