Abstract : The development is described of an on-line computer system for symbol manipulation in which a user can arbitrarily define symbols and rules for operating with these symbols, and then instruct the computer on-line to selectively apply the rules. At the basis of the system is a small set of elementary symbol manipulation operators which can be programmed on-line to carry out more complex symbolic processes. The application of the system to algebra is presented; the resultant system for algebraic symbol manipulation allows the user to have the computer apply rules of algebra on-line to transform mathematical expressions which he has input in a natural form.
