kAnswer 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.

•The largest value that the answer memory can hold is 15 digits for the mantissa and 2 digits 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.

kPerforming 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

Continuous calculations can also be used with Type B functions (x2, x–1, x!, on page 2-3), +, –, ^(xy), x', ° ’ ”, etc.
