Your calculator has eight preset variables named A, B, C, D, E, F, X, and Y. You 
can assign values to variables and also use the variables in calculations. 

 

To assign the result of 3 + 5 to variable A

 

 

                                     3 

+ 5 1t(STO)y(A) 

 

To multiply the contents of variable A by 10

 

 

                    (Continuing)     

Sy(A)* 10 = 

 

To recall the contents of variable A    (Continuing)     

ty(A) 

 

To clear the contents of variable A          0 

1t(STO)y(A) 

You can add calculation results to or subtract results from independent 
memory. The “M” appears on the display when there is any value other than 
zero stored in independent memory. 

 

To clear the contents of M                       0 

1t(STO)l(M) 

 

To add the result of 10 

× 5 to M        (Continuing)     10 * 5 l 

 

To subtract the result of 10 + 5 from M 

       

 

 

                       (Continuing)     10 

+ 5 1l(M–) 

 

To recall the contents of M                 (Continuing)      

tl(M) 

Note:  Variable M is used for independent memory. 

Ans memory, independent memory, and variable contents are retained even 
if you press 

A, change the calculation mode, or turn off the calculator. 

PreAns memory contents are retained even if you press 

A and turn off the 

calculator without exiting the COMP Mode. Perform the following procedure 
when you want to clear the contents of all memories.
!9(CLR)2(Memory)=(Yes) 

You can use the ÷R function in order to obtain the quotient and remainder 
in a division calculation.
