Note: To stop (break) a calculation, press ´. The unknown variable shows the value
being tested when the break occurred.
Using the solution and your entered values, the left and right sides of the equation are
evaluated separately.
left N rt shows the difference, which indicates the solution’s
accuracy. The smaller the value, the more accurate the solution. If the solution is
precise,
left N rt=0 .
Note: An iterative process is used to solve an equation. If the iterative process cannot
converge on a solution, this error occurs.

You can graph an equation’s solutions any time after defining the known variables, either
before or after you solve for the unknown variable. By graphing the solutions, you can
If you: Do this:

values Edit the equation or variable values.
Want to find a different
solution for an equation
with multiple solutions Enter an initial guess and/or a new set of
bounds close to the other solution.

• The left N rt value may be small enough for
you to accept the result.
• If not, enter a different set of bounds.
