'''Yacas''' {{IPAc-en|ˈ|j|æ|k|ə|s}} is a general-purpose [[computer algebra system]].  The name is an acronym for ''[[Yet another|Yet Another]] Computer Algebra System''.
Released under the [[GNU Lesser General Public License]], Yacas is [[free software]].
YACAS is a program for symbolic manipulation of mathematical expressions. It uses its own [[programming language]] designed for symbolic as well as [[arbitrary-precision arithmetic|arbitrary-precision]] numerical computations. The system has a library of scripts that implement many of the symbolic algebra operations; new algorithms can be easily added to the library. YACAS comes with extensive documentation covering the scripting language, the functionality that is already implemented in the system, and the algorithms used. Its development started in early 1999.<ref name="released1999">{{citation|chapter=Yacas : A Do-It-Yourself Symbolic Algebra Environment|first1=Ayal Z. |last1=Pinkus |first2=Serge |last2=Winitzki|title=Artificial Intelligence, Automated Reasoning, and Symbolic Computation|series=Lecture Notes in Computer Science|year=2002|volume=2385|pages=332–336|publisher=[[Springer (publisher)|Springer]]|doi=10.1007/3-540-45470-5_29|isbn=978-3-540-43865-6}}</ref>
Yacas handles input and output in plain [[ASCII]] or in [[OpenMath]], either interactively or in batch mode.
