Pressing d four times successively displays the numbers in the Y-, Z-, and
T-registers and returns the numbers to their original registers.

One-number mathematics and number-alteration functions — y, r, ¿, >,
e, B, Ñ, and T — use only the number in the displayed X-register.
When the key is pressed, the function is performed upon the number in the
X-register, and the answer is then placed into the X-register. The stack does not lift,
so the number formerly in the X-register does not get copied into the Y-register; but
this number is copied into the LAST X register. The numbers in the Y-, Z-, and
T-registers are not affected when a one number function is performed.

To perform an arithmetic operation, the numbers are positioned in the X- and
Y-registers just as you would write them vertically on paper: the number you would
write on top goes in the Y-register, and the number you would write on the bottom
goes in the X-register. For example, to do each of the four arithmetic calculations
shown below, you would put the 8 in the Y-register (using \ and then key the 2
into the displayed X-register.)
