The Equation Solver
The Equation Solver (the SOLVE menu) stores equations that you enter
and creates menus for them. You can then use those menus to do
calculations. Enter Solver equations in algebraic form regardless of the
calculation mode (ALG or RPN).
The Solver can store many equations—the number and length of
equations is limited only by the amount of memory available. The
equations are stored in a list.

Solver Example: Sales Forecasts
Suppose part of your job includes making sales forecasts, and that these
forecasts are revised based on new information. For instance,
 A change in the price of the product will affect sales by a forecasted
percentage, A%.
 A change in sales-force training will affect sales by a forecasted
percentage, B%.
 A competitor’s new product will affect sales by a forecasted
percentage, C%.
