Storing and Recalling Numbers
The
s
key copies a number from the calculator line into a
designated storage area, called a storage register. There are ten
storage registers in calculator memory, numbered 0 through 9. The
R
key recalls stored numbers back to the calculator line.
lf there is more than one number on the calculator line,
s
stores only
the last number in the display.
To store or recall a number:
1. Press
s
or
R
. (To cancel this step, press
<
.)
2. Key in the register number.
The following example uses two storage registers to do two calculations
that use some of the same numbers.
