This program is a tool for solving algebra problems.
Alged cannot solve the problem for you; you need to think. But
it can relieve the tedium of working with large formulas, and
it has rewrite rules to help simplify as you go. The Alged screen
has a menu at the top and a work area at the bottom. You manipulate
the formulas in the work area by clicking on parts of them and
then clicking on the menu. Commands include: Simplify, Distribute,
Calculate, Associate, Comm-Deno (create a common denominator),
Poly-Coef (collect the coefficients of a polynomial), Poly-Div
(polynomial division), FactPoly (factor a polynomial), Substitute,
ExpJoin (join exponents of common base), etc.
