PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves...), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers etc., and a lot of transcendental functions.
PARI/GP is composed of two parts: a C library called PARI and an interface, gp, to this library. GP scripts are concise, easy to write, and resemble mathematical language. (Terminology: the scripting language of gp is called GP.)
PARI was written by Henri Cohen and others at Université de Bordeaux; Aurel Page is the current project leader. gp was originally written by Dominique Bernardi, then maintained and enhanced by Karim Belabas and Ilya Zakharevich, and finally rewritten by Bill Allombert.
Getting PARI/GP
PARI/GP can be used in many different operating systems. This is a reasonably comprehensive list of currentlysupported systems; for other systems, please use the mailing lists.

Coding with PARI
The most common way to use PARI is through the gp calculator, using its own scripting language, GP. But there are other interfaces to PARI beside gp:
 PariGP on EmacsWiki, PariEmacs
 Paritty
 pariGUIde
 vimnotebook (see also the author's video on using gp from vim)
 Jupyter kernel
If you want to program with PARI, many languages are supported:
 C: PARI is written in C, so it's very easy to either write your own programs or extend gp using C.
 The gp2c utility converts GP scripts into executable C code.
 For use with the Gnu Mpc library, there is also PariGnump.
 PariTwine is a glue library for various math libraries including GMP, GNU MPFR, GNU MPC, FLINT, ARB and CMH.
 C++: PARI can be used directly in C++. The code is intentionally written in a C++compatible style.
fpermissive
may be useful when compiling with g++.  Python:
 SageMath (or SAGE) is a Pythonbased system that includes GP among others
 paripython
 cypari/cypari2 is a fork of the GP component of SageMath (see also the voluminous CyPari2 Documentation)
 Perl:
 Common Lisp: Use Pari (CLISP).
 Mathematica: A quick tutorial using MathLink is available.
