The Early Republic
The Information Age

MACSYMA (Project MAC’s SYmbolic MAnipulation System) is a set of programs used to solve problems in algebra, calculus, linear algebra, and differential equations. Development began in 1968 as part of planning for a new computer to be built at MIT known as the MAC. In 1982, MIT granted Symbolics, Inc., a license to sell a commercial version of MACSYMA. The program has also been modified and distributed under other names. 

The physicist Stephen Wolfram and his colleagues developed this
system of programs for technical and scientific computing beginning in
1986. Mathematica, released in 1988, was particularly noteworthy for its
graphic capabilities and ease of editing. 
Computer programs can both compute numbers and manipulate the
symbols in equations. Early programs for symbolic manipulation were
written in sophisticated computer languages and only ran on large
computers. 
Albert Rich and David Stoutemyer wrote a computer algebra program for microcomputers, which they named muMath. In 1979, Stoutemyer and Rich formed a partnership to produce muMath. In 1988 the partnership, now named Soft Warehouse, Inc., introduced a successor to muMath, DERIVE. More recently, staff from Soft Warehouse coauthored programs embodied in the TI92 graphing calculator.
