is displayed in the last line of the editor.
diff
is the
difference between the left and right sides of the equation. A solid
square in the first column next to

N
rt=
indicates that the
equation has been evaluated at the new value of the variable for
which you solved.
Editing an Equation Stored to eqn
To edit or replace an equation stored to
eqn
when the interactive
equation solver is displayed, press
}
until the equation editor is
displayed. Then edit the equation.
Equations with Multiple Roots
Some equations have more than one solution. You can enter a new
initial guess or new bounds to look for additional solutions.
Further Solutions
After you solve for a variable, you can continue to explore solutions from
the interactive solver editor. Edit the values of one or more variables.
When you edit any variable value, the solid squares next to the previous
solution and

disappear. Move the cursor to the variable for
which you now want to solve and press
