The Equation Solver allows you to solve for one unknown
one-letter variable in an equation containing up to 5 one-letter
variables. By default, the equation is assumed to be equal to 0;
however, you can set the equation equal to any real number
(or an expression that results in a real number).
The screen you see when you select
Solver
depends on
whether an equation has been defined previously.
To exit Solver and return to the Home screen, press
