# Sage

SAGE is a framework for number theory, algebra, and geometry computation that is initially being designed for computing with elliptic curves and modular forms. The long-term goal is to make it much more generally useful for algebra, geometry, and number theory. SAGE provides a (Python) interpreter interface to several important C/C++ libraries:

- MPFR -- real number arithmetic,
- NTL -- Victor Shoup's number theory library,
- GMP -- arbitrary precision integer and floating point arithmetic package.

- These systems come with SAGE, and there is an interface to each:
- GAP -- group theory and combinatorics
- PARI -- algebraic number theory
- Singular -- polynomial computations and algebraic geometry
- Maxima -- symbolic algebra
