expression.

# The value stored in the answer memory is
always dependent on the result produced
by the last calculation performed. If history
contents include operations that use the
answer memory, editing a calculation may
affect the answer memory value used in
subsequent calculations.
- If you have a series of calculations that use
the answer memory to include the result of the
previous calculation in the next calculation,
editing a calculation will affect the results of all
the other calculations that come after it.
- When the fi rst calculation of the history includes
the answer memory contents, the answer
memory value is “0” because there is no
calculation before the fi rst one in history.
