Variables (A, B, C, D, E, F, X, Y)
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 =(STO)E(A)
8
To multiply the contents of variable A by 10
(Continuing)
E(A) 10
80
To recall the contents of variable A (Continuing) =E(A) 8
To clear the contents of variable A 0 =(STO)E(A) 0
Independent Memory (M)
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 =(STO)J(M)
0
To add the result of 10 s 5 to M (Continuing) 10 5 J 50
To subtract the result of 10 + 5 from M
(Continuing) 10 5 J(M–) 15
To recall the contents of M (Continuing) =J(M) 35
Note: Variable M is used for independent memory.
Clearing the Contents of All Memories
Ans memory, independent memory, and variable contents are retained even
if you press
, change the calculation mode, or turn off the calculator.
Perform the following procedure when you want to clear the contents of
all memories.
(CLR)(Memory)(Yes)
