• To solve 2[
2
+ [ − 3 = 0, for example, press (Polynomial) in
step 2. Use the Coefficient Editor that appears to input
213.
• Pressing will clear all of the coefficients to zero.
4. After all the values are the way you want, press .
• This will display a solution. Each press of will display another
solution. Pressing while the final solution is displayed will return to
the Coefficient Editor.
• A message appears to let you know when there is no solution or when
there are infinite solutions. Pressing or will return to the
Coefficient Editor.
• You can assign the currently displayed solution to a variable. While
the solution is displayed, press and then the key that
corresponds to the name of the variable to which you want to assign
it.
• To return to the Coefficient Editor while any solution is displayed,
press .
To change the current equation type setting: Press (Simul
Equation) or (Polynomial), and then press , , or . Changing
the equation type causes the values of all Coefficient Editor coefficients to
change to zero.

Using Spreadsheet
To perform the operations in this section, first enter the Spreadsheet Mode.
The Spreadsheet Mode makes it possible to
perform calculations using a 45-row × 5-
column (cell A1 to E45) spreadsheet.
(1) Row numbers (1 to 45)
(2) Column letters (A to E)
(3) Cell cursor: Indicates the currently
selected cell.
(4) Edit box: Shows the contents of the cell
where the cell cursor is currently located.
Important: Any time you exit the Spreadsheet Mode, turn off the calculator
or press the key, every input into the spreadsheet is cleared.
Inputting and Editing Cell Contents
You can input a constant or a formula into each cell.
