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.

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

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.
