Cambridge Algebra System (CAMAL) is a computer algebra system written in Cambridge University by David Barton, Steve Bourne, and John Fitch. It was initially used for computations in celestial mechanics{{Cite book |title=Automatic algebraic manipulation and its application to the lunar theory |first=Stephen Richard |last=Bourne |publisher=University of Cambridge |year=1969}}{{cite journal |title=Literal Expressions for the Co-Ordinates of the Moon.
