of the equation using the value of the solution; this is the calculator’s way of checking the
solution.
You can also enter a formula, assign values, and solve for a specic variable using the Solver
function of the Equation Editor.
Note: Selecting q(REPT) will take you back to the previous screen where you can edit and
