for the exponent.
• Answer memory contents are not cleared when you press the A key or when you switch
power off.

• Performing an operation that assigns a value to an Alpha memory (such as
faal(B) w), answer memory contents are updated in the Math input/output mode
but not in the Linear input/output mode.
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 =
Ab/dw
(Continuing) *dw
