Arithmetic and the Stack
When you press the addition key the contents of X and Y are added
together. The stack then drops, with t reproduced in T and Z, z
transferred to Y, y + x transferred to X, and x transferred to LAST X
(location 0).

The same dropping action takes place with any operator (+,—, x, or ~);
the result is placed in x.
EXAMPLE

All problems can be solved by keying in the numbers in the same order
as they appear in the original expression, that is, from left-to-right.
To work a problem, key in the first number. If there is an operation
you can perform at this point (/x, 1/x), do it. If there is not, press
ENTER?. Now key in the next number. Perform any operation that can
be done (+, —, x, +, x?,4/X%, 1/x, etc.). If there is no operation you can
perform, ENTER? this number and repeat the procedure.
