You can also edit the calculation expressions that are maintained by the history function
and recalculate. This will recalculate all of the expressions starting from the edited
expression.

To change “1+2” to “1+3” and recalculate
Perform the following operation following the sample shown above.

# 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.
