→History: i maintain moving this section to the bottom is chronological. At least, there's nothing in the text to suggest this happened before 1987, which is currently the item following it. If they are introduced earlier, there should be an associated date. |

Using [[Lisp (programming_language)|Lisp]] as the programming basis, [[Carl Engelman]] created [[MATHLAB]] in 1964 at [[MITRE]] within an artificial-intelligence research environment. Later MATHLAB was made available to users on PDP-6 and PDP-10 systems running TOPS-10 or TENEX in universities. Today it can still be used on [[SIMH]] emulations of the PDP-10. MATHLAB ("'''math'''ematical '''lab'''oratory") should not be confused with [[MATLAB]] ("'''mat'''rix '''lab'''oratory"), which is a system for numerical computation built 15 years later at the [[University of New Mexico]].
The first popular computer algebra systems were [[muMATH]], [[Reduce computer algebra system|Reduce]], [[Derive (computer algebra system)|Derive]] (based on muMATH), and [[Macsyma]]; a popular [[copyleft]] version of Macsyma called [[Maxima (software)|Maxima]] is actively being maintained. [[Reduce (computer algebra system)|Reduce]] became free software in 2008.<ref>{{Cite web|title = REDUCE Computer Algebra System at SourceForge|url = http://reduce-algebra.sourceforge.net|website = reduce-algebra.sourceforge.net|access-date = 2015-09-28}}</ref> As of today,{{when|date=October 2016}} the most popular commercial systems are [[Mathematica]]<ref>[http://history.siam.org/oralhistories/gonnet.htm Interview with Gaston Gonnet, co-creator of Maple] {{webarchive|url=https://web.archive.org/web/20071229044836/http://history.siam.org/oralhistories/gonnet.htm |date=2007-12-29 }}, SIAM History of Numerical Analysis and Computing, March 16, 2005.</ref> and [[Maple (software)|Maple]], which are commonly used by research mathematicians, scientists, and engineers. Freely available alternatives include [[SageMath]] (which can act as a [[Front and back ends|front-end]] to several other free and nonfree CAS). Other significant significant systems include [[Axiom (computer algebra system)|Axiom]], [[Maxima (software)|Maxima]], [[Magma (computer algebra system)|Magma]], and [[SageMath]].▼
In 1987, [[Hewlett-Packard]] introduced the first hand-held calculator CAS with the [[HP-28 series]], and it was possible, for the first time in a calculator,<ref name="Nelson">{{cite web | title=Hewlett-Packard Calculator Firsts | first=Richard | last=Nelson | publisher=Hewlett-Packard | url=http://h20331.www2.hp.com/Hpsub/cache/392617-0-0-225-121.html | archive-url=https://web.archive.org/web/20100703031935/http://h20331.www2.hp.com/Hpsub/cache/392617-0-0-225-121.html | archive-date=2010-07-03}}</ref> to arrange algebraic expressions, differentiation, limited symbolic integration, Taylor series construction and a ''solver'' for algebraic equations. In 1999, the independently developed CAS [[Erable]] for the [[HP 48 series]] became an officially integrated part of the firmware of the emerging [[HP 49/50 series]], and a year later into the [[HP 40 series]] as well, whereas the [[HP Prime]] adopted the [[Xcas]] system in 2013.
