Casio How to Use Memory in Calculators
Page 16

Using the memories

The calculator has an independent memory that can store the result of a calculation. In addition there are six pronumerals A, B, C, D, X and Y which may be assigned values.

The independent memory M

Before you start using the memory, check that there is nothing in the memory. In the following screen shot the small M in the top left hand corner of the screen indicates that a value is stored in the memory. The contents of the memory can be cleared by pressing 0qJ(STO) m.

Store the result of a calculation by pressing m.

In the above screen 15 is stored in the M memory. The button sequence to add the memory to 12 is: 12+Jmp.

Caution! The calculator ‘remembers‛ the values stored in the memories even after the machine has been turned off. If you place a value in the memory without first clearing the memory, the calculator will add the new value to the value already in the memory.

Storing values in A, B, C, D, X or Y

In the above screen the result of 3 + 5 is being stored in A. The button sequence is: 3+5SHIFT J(STO) z.

Using values stored in A, B, C, D, X or Y

The button sequence for the above screen is:

3d+Jzdp
