that is, A-x.
Recall arithmetic uses (rcl](T)/ fRcTlFI, rRCLTxl, or fRCpm 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; all other stack
registers are unaffected.
New x = Previous x {+, —, x, ^-} Variable
For example, suppose you want to divide the number in the X-register
(3, displayed) by the value in A (12). Press fRCLl f+1 A. Now x = 0.25,
while 12 is still in A.*

*Recall arithmetic savesmemoryspace in programs. Using IRCL I\T\ A (oneinstruction) uses
half as much memory as IRCL I A, [T] (two instructions).
