Recall Arithmetic

Recall arithmetic uses a K™, Ky, or Kpto 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 KpA. 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 KA, ™(two instructions).
