180  12: The Equation Solver 

File name : English-M02-1-040308(Print).doc   Print data : 2004/3/9

The process of finding a solution iteratively is very complex. There are 
four possible outcomes. Refer to “Solver Calculations” in appendix B for 
additional descriptions of these outcomes. 
 

„

 

Case 1: 

The calculator displays a result. It is very likely that this is a 

solution to the equation. To check how good this result is, you can 
repeat the calculation by pressing the menu key for the variable you 
solved for. If the two sides of the equation have not been calculated to 
be exactly equal, the calculator displays a message with the values 
for the left and right sides of the equation. Read “Solver Calculations” 
in appendix B for an explanation of the meaning of this display. 

„

 

Case 2:

 The calculator displays a message with the calculated, 

unequal values of the left and right sides of the equation. The Solver 
has found a possible solution, but you must interpret its validity. To see 
the questionable solution, press 

<

 or 

C

. Refer to “Solver 

Calculations” in appendix B for more information. 

„

 

Case 3:

 The calculator displays

    

 

 

. The Solver cannot begin the search with the 

current guesses. Press 

<

 or 

C

 to view the starting guesses. To 

supply new guesses, see “Entering Guesses,” below. 

„

 

Case 4:

 The calculator displays 

       

 

  

 

    

. Check 

to see if your equation and stored values are correct. If the equation is 
correct,  you  might  be  able to  find  a  solution  by  entering  very  good 
guesses. 

 

Halting and Restarting the Iterative Search 

When the Solver is iteratively searching for a solution (in other words, 
when the Solver is displaying sets of estimates), you can halt the 
calculation by pressing any key except 

@

. The calculator displays the 

message 

          

. To see the best estimate the Solver has 

found so far, press 

C

 or 

<

. You can restart the search from where 

it left off by pressing the menu key for the variable you are solving for. 
Or, you can restart the search using your own guesses (see “Entering 
Guesses,” below).
