This section describes the mode switches, data entry keys, and operating keys provided

on your calculator. The following terms are used in discussing your calculator’s

operation:

• The accumulator is the area of the calculator’s logic that stores a running total of

the results of addition and subtraction operations. It is the “adding machine” portion

of the calculator.

• The calculating register is the area of the calculator’s logic where the intermediate

and final results of multiplication, division and percentage calculations are stored.

The contents of the calculating register do not affect the accumulator.

• The keyboard register is the area of the calculator’s logic that stores the value that

will immediately be used in the next calculation.

• The item count register is the area of the calculator’s logic that counts your

entries into the accumulator

• The memory register is the area of the calculator’s logic that accumulates

amounts you add to or subtract from the memory. Because the memory register is

independent of the accumulator and the calculating register, it retains its value until

you clear it with the Memory Total (MT) key.
