Recalls the previous answer. Use this key to incorporate the
answer to the previous calculation into an expression.

3 | 3 E
Subtract the value of the previous
answer from "10".
1 0 - @ b E
b can be considered as a variable; its value is automatically
set when E is pressed. If b is not empty, then pressing
+, -, |, or = will recall "Ans" and places it at
the beginning of an expression. If "1" was the previous answer,
then pressing + 4 E will result in "5".
Recalls the previous entry. This is useful when you want to modify
the previous entry, rather than re-entering the whole expression.

Executed expressions are stored in a
temporary memory in the executed order. If the temporary
memory is full, the oldest data is automatically deleted. Be aware
that e may not function on these occasions.
A maximum of 160 bytes can be stored in the temporary memory.
The capacity may vary when there are division codes between
expressions.
When switching from equation edit mode to one-line edit mode
in the SETUP menu, all the numerical and graph equations stored
in the temporary memory are cleared and cannot be recalled.
