Basic Cumulative Memory (M+)
Example:
Store 100 into M+, add 200, and then subtract 50. Display the total,
average, and total count. Clear the Memory:

1 0 0 µ M+ 100.
2 0 0 µ M+ 200.
5 0 Ç µ (M-) M- 50.
® µ TTL 250.

Store 1,575 Square Yards into M2 and recall the value:
KEYSTROKE DISPLAY
1 5 7 5 y y ß 2 M-2 1575. SQ YD
O o 0.
® 2 M-2 1575. SQ YD
Note: To Clear M1-M3: Values stored in M1-M3 will remain permanently stored, even
after you turn the calculator off. You will never need to clear the storage registers;
