Recall Arithmetic
Recall arithmetic uses a
K
,
K
y
, or
K
p
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
K
p
A. Now x = 0.25, while 12
is still in A. Recall arithmetic saves memory in programs: using
K
A
(one instruction) uses half as much memory as
K
A,
(two instructions).
