The Representation of Equations and ... (Mathematica Tutorial)

Mathematica treats equations as logical statements. If you type in an equation like x^2+3x==2, Mathematica interprets this as a logical statement which asserts that x^2+3x is ...

ToNumberField (Built-in Mathematica Symbol)

ToNumberField[a, \[Theta]] expresses the algebraic number a in the number field generated by \[Theta]. ToNumberField[{a_1, a_2, ...}, \[Theta]] expresses the a_i in the field ...

Multinomial (Built-in Mathematica Symbol)

Multinomial[n_1, n_2, ...] gives the multinomial coefficient (n_1 + n_2 + ...)!/(n_1! n_2! ...).

C/C++ Language Interface (Mathematica Guide)

Mathematica supports several levels of interfacing to C and C++ programs. You can create "installable" C programs where C functions are directly connected to Mathematica ...

BeginPackage (Built-in Mathematica Symbol)

BeginPackage["context`"] makes context` and System` the only active contexts. BeginPackage["context`", {"need_1`", "need_2`", ...}] calls Needs on the need_i.
