Question about Office Equipment & Supplies
MR is Memory Recall
MC is Memory Clear
M+ is Memory add
M- is Memory subtract
These are used to add and subtract the answers to multi-step equations so you can do the small steps with the calculator, then store, change or recall the total as needed. You might add a long string of numbers in groups this way. Or you can do all operations in one parenthesis, then just store the total of each.
A good problem to illustrate this would be : (123 x 3) + (55 - 24) + (10^2) - (7 x 8) = ???
Using MR, M+ and M-, you can do each one as a group, and only store the answers. 123 x 3 = 369 so M+ to put 369 in memory. Clear it from the calculator. 55 - 24 = 31, so M+ to put this in memory and add to the 369 already there. Clear it from the calculator. 10^2 = 100, so M+ this to memory also to add it. Clear it from the calculator. 7 x 8 = 56 so M- this to SUBTRACT it from memory. Clear it from the calculator if desired. Now, when you then hit MR, you will get the total of all of these small equations in parenthesis -- 444.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

M- subtracts the displayed number from the total in memory.
M+ adds the displayed number to the total allreday in memory.
For the other two, I can only guess: MC Clears memory, MR recalls from memory. But that should not be difficult to verify on your calculator.
Hope it helps.

Testimonial: "Problem solved. Thanks for helping."
Those are the "Memory" function keys.
[MC] = "Memory Clear"
[MR] = "Memory Recall"
[M+] = "Add to Memory"
[M-] = "Subtract from Memory"
This is used when you want to store a set of numbers or a total, temporarily, while you do another calculation.
1 + 2 = [M+] ( you just placed a "3" into Memory)
Now enter this:
4 + 4 = (you have "8" on the display)
Now press these three keys: - [MR] =
Your display shows "5"
What you did was to take "8" and subract "3" that you stored in Memory. That equals 5.
Go through this again and it works!

Testimonial: "Thanks I coudn't figure it out, there were no imstructions. I was also lokking for something to set the decimal point automaticly. Again thanks."
Can the memory function be turned off?

SOURCE: What does MC, MR, &
Welcome to Fixya. Heres the meaning that you're looking for.
MC - Memory Clear. this clears all contents of the memory
MR - Memory Recall. This displays the current content in the memory
MS - Memory Save. This saves the current display to memory.
M+ - Memory Add. This adds the current figure to the value already present in memory.
Thanks for using Fixya.

The calculator has 10 memories (0 to 9)
To store a number (13) in memory 6 type 13 [STO] 6
To erase the content of memory 6 (M6) store 0 in int: 0 [STO] 6
To recall the content of memory location M7 press [RCL]7
To operate on the content of memory location M5 the syntax is [STO] [Op] 5, where [Op] is the operation symbol [+], [-],[x], [/] [y^x]
Ex: to raise the content of memory location 4 to the power of the displayed value, you press [STO][Y^x] 4
To clear all 10 memory locations
press [2nd][MEM][2nd][CLR WORK]
In short, although you do not have the keys you are accustomed to, you have a lot more. And please do not blame me if you feel disappointed.

SOURCE: What do calculator buttons on
Not sure what they all mean but
ON/C turns calculator on or Cancels the current entry % divides by 100 or percent MC - memory clear M+ add to what is stored in memory M- subtract from what is in memory
