Arithmetic Calculations With Constants
There are three ways (without using a storage register) to manipulate the
memory stack to perform repeated calculations with a constant:
1.
Use the LAST X register.
2.
Load the stack with a constant and operate upon different
numbers. (Clear the X-register every time you want to change
the number operated upon)
3.
Load the stack with a constant and operate upon an
accumulating number. (Do not change the number in the X-
register.)
LAST X. Use your constant in the X-register (that is, enter it second) so
that it always will be saved in the LAST X register. Pressing |K will
retrieve the constant and place it into the X-register (the display). This can
be done repeatedly.
