• Internal calculations are performed using a 15-digit mantissa, but results are displayed

using a 10-digit mantissa and a 2-digit exponent.

• It may take considerable time for the calculation result of a high-order equation of 3rd degree

or higher to appear on the display.

• An error occurs if the calculator is unable to find a solution.

• High-order equation calculations may not produce accurate results when the equation has

multiple

solutions.

• After calculation is complete, you can press

1(REPEAT), change coefficient values, and

then

re-calculate.

3. Solve Calculations

The Solve calculation mode lets you determine the value of any variable in a formula without

having to solve the equation.

Important!

• You can input either an upper-case X (

a+(X)) or lower-case

x

(

v) for variable X.

Both “X” and “

x

” refer to the same variable.

1. From the Main Menu, enter the Equation mode.

2. Select the SOLVER mode, and input the equation as it is written.
