# 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 first calculation of the history includes
the answer memory contents, the answer
memory value is “0” because there is no
calculation before the first one in history.
