Chapter 2: General Information

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 = 32π) and volume of a cylinder (V = 5S) using the last answer memory.

1.Press j 3 A @ s e.

• The area of the base is now calculated.

• The number 28.27433388 is held in ANS memory.

2.Press j 5 ; < e.

•You now have the volume of the cylinder.

h = 5

r = 3

The last answer is cleared (i.e. set to 0) if you

press the RESET switch, change the mode or memory clear operation (@ P 1 y), 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.
