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 calculators 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. Each positive or negative entry is counted as one item..

• 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.
