k Answer Function
The Answer Function automatically stores the last result you calculated by pressing
w (unless the w key operation results in an error). The result is stored in the answer
memory.
u To use the contents of the answer memory in a calculation
Example 123 + 456 = 579
789 – 579 = 210
A bcd+efg w
hij- !- (Ans)w
In the Math input mode, the answer memory is refreshed with each calculation. Note,
however, that the answer memory content recall operation is different from that used in
the Linear input mode. For details, see “History Function” (page 2-2-6).
k Performing Continuous Calculations
Answer memory also lets you use the result of one calculation as one of the arguments in
the next calculation.
Example 1 ÷ 3 =
1 ÷ 3 × 3 =
A b/d w
(Continuing)*d w
Continuous calculations can also be used with Type B functions (

Special Functions
# The largest value that the answer memory
can hold is 15 digits for the mantissa and 2
digits for the exponent.
# Only numeric values and calculation results
can be stored in answer memory.
# Answer memory contents are not cleared when
you press the A key or when you switch power
off.
# When “Linear” is selected as the Input Mode,
answer memory contents are not changed by an
operation that assigns values to Alpha memory
(such as: f a av (A)w ).
