For example, suppose you want to reduce the value in A(15) by the number in the
X–register (3, displayed). Press
e Ã
A. Now A = 12, while 3 is still in the
display.

Recall Arithmetic
Recall arithmetic uses
h Ù
,
h Ã
,
h ¸
, or
h ¯
to do
arithmetic in the X–register using a recalled number and to leave the result in the
display. Only the X–register is affected.
New x = Previous x {+, –,

} Variable
For example, suppose you want to divide the number in the X–register (3,
displayed) by the value in A(12). Press
h ¯
A. Now x = 0.25, while 12 is
still in A. Recall arithmetic saves memory in programs: using
h Ù
A (one
instruction) uses half as much memory as
h
A,
Ù
(two instructions).

Example:
Suppose the variables D, E, and F contain the values 1, 2, and 3. Use storage
arithmetic to add 1 to each of those variables.
