leftNrt indicates that the equation has been evaluated at the new value of the
variable for which you solved.

Some equations have more than one solution. You can enter a new initial guess or new
bounds to look for additional 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
leftNrt=diff disappear. Move the cursor
to the variable for which you now want to solve and press ƒ\.

The TI-84 Plus solves equations through an iterative process. To control that process,
enter bounds that are relatively close to the solution and enter an initial guess within
those bounds. This will help to find a solution more quickly. Also, it will define which
solution you want for equations with multiple solutions.
