Clearing Numbers

Clearing One Number. Clearing the X-register puts a zero in it. The next number you key in (or recall) writes over this zero.

There are two ways to clear the number in the X-register:

„Press <.

„Press C.

For example, if you wanted to enter 1 and 3 but mistakenly entered 1 and 2, these keystrokes would correct it:

1

1

E

Clearing the Entire Stack. Pressing @c clears the X-register to zero and eliminates the Y-, Z-, and T-registers (reducing the size of the stack to one register). The stack expands again when you enter more numbers.
