If you know PARI/GP, please write code for some of the tasks not implemented in PARI/GP.
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 and is now maintained by Karim Belabas. gp was originally written by Dominique Bernardi, then maintained and enhanced by Karim Belabas and Ilya Zakharevich, and finally rewritten by Bill Allombert.

Coding with PARI[edit]
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.
 C++: PARI can be used directly in C++. The code is intentionally written in a C++compatible style.
fpermissive
is sometimes useful when compiling with g++.  Python:
 SageMath (or SAGE) is a Pythonbased system that includes GP among others
 paripython
 cypari is a fork of the GP component of SageMath
 Perl:
 Common Lisp: Use Pari (CLISP).
 Mathematica: A quick tutorial using MathLink is available.
