Using the last answer memory
The calculator always keeps the most recent answer in ANS memory and
replaces it with the new answer every time you press an ending instruction
(
e
,
x
etc.). You may recall the last answer and use it in the next
equation.
Example
Evaluate the base area (S = 3
2
π
) and
volume of a cylinder (V = 5S) using the last
answer memory.

The last answer is cleared (i.e. set to 0) if you
press the RESET switch, change the mode or memory clear operation (

), but not if you turn the calculator off.
Global variable M
Using the M memory, in addition to the features of global variables, a value
can be added to or subtracted from an existing memory value.
