123 + 456 = 579

123 + 456 =

789 – 579 = 210

(Continuing) 789 -G=

Independent Memory (M)

You can add calculation results to or subtract results from independent

memory. The “M” appears on the display when there is any value other than

zero stored in independent memory.

To clear the contents of M 0 S 0

To assign the result of 2 + 8 to M 2 + 8 S 10

To add the result of 10 × 5 to M (Continuing) 10 * 5 l 50

To subtract the result of 10 + 5 from M

(Continuing) 10 + 5 m 15

To recall the contents of M (Continuing) M 45

Note: You also can call M and use it in a calculation you are inputting.

Clearing the Contents of All Memories

Ans memory and independent memory contents are retained even if you

press A, or turn off the calculator. Perform the following procedure when

you want to clear the contents of all memories.

r2(Memory)=(Yes)

Remainder Calculations

You can use the ÷R function in order to obtain the quotient and remainder

in a division calculation.

To calculate the quotient and remainder of 5 ÷ 2

5 u 2 =

Quotient Remainder

Note: • Only the quotient value of a ÷R calculation is stored in Ans memory.

• Assigning a remainder calculation result to independent memory (M) will

cause only the quotient value to be assigned. For example, assigning the

result of the remainder calculation 5÷R2 (5 u 2 S) will result in 2 being

assigned to M. Adding a remainder calculation result to or subtracting result

from M will add or subtract only the quotient value. • If a ÷R calculation is part

of a multi-step calculation, only the quotient is passed on to the next operation.

(Example: 10 + 17 u 6 = → 10 + 2) • Operation of the F, and e keys

is disabled while a remainder division result is on the display.
