• 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.
