Memory is a function that is part of nearly all basic four-function and scientific calculators. The memory is basically a variable that can be used to store a single number separately from the one on the screen, for later recall.
The buttons used to manipulate the memory usually have these labels (not all calculators have them):
M+ Adds the number on the screen to the one in the memory.
M- Subtracts the number on the screen from the one in the memory. On calculators with no M- button, you can do this by negating the number and pressing M+
MR (or RCL) Enters the number in the memory onto the screen.
MRC Pressing this once is the same as MR. Pressing it twice will clear the memory.
MS (or STO, M=>) Stores the number on screen into the memory, overwriting whatever number is already in the memory.
Garphing and CAS calculators don't have a single 'memory' variable, but will allow you to store numbers into arbitrarily named variables like x using commands similar to:
Define x = 5 x := 5 5 -> xStores 5 into the variable x.
x Displays the value of x on screen.
x ² + 5 x - 14 What use would a CAS calculator be if you couldn't use x in an expression?

What does m- stands for on a calculator?
You can subtract whatever number you have entered into memory.
What does MC mean on a calculator?
Usually MC is Memory Clear.There will often also be:MR - Memory RecallM+ - Memory PlusIf you have a MRC button, then it is Memory Recall/Clear. Pressing it once will recall the memory; immediately pressing it a second time will recall the memory and clear it at the same time.
What does MR on a calculator mean?
Memory Recall-Use this button to put the contents of the memory onto the display. The default memory is number zero. To display other memories, first press the shift button and then the MR button and select the required memory.

What those this mean M plus IN a calculator?
it means memory
Does a calculator have buttons?
Yes, You wouldn't be able to do too much with a calcultor with no buttons...

How do you use the m buttons on a calculator?
These buttons work with the calculator's memory, which stores one number: MC = Memory Clear sets the memory to 0 MR = Memory Recall uses the number in memory, acts as if you had keyed in that number yourself MS = Memory Store puts the number on the display into the memory M+ = Memory Add takes the number on the display, adds it to the memory, and puts the result into memory The buttons can be handy for doing repeated calculations with a single number. For instance, if you wanted to multiply a bunch of numbers by pi, you could key in the following: 3.14159.. MS (stores the number) 4 x MR = (gives you 4 times pi) 25 x 25 x MR = (gives you 25x25 times pi) The M+ button can be handy for figuring out complicated expressions if you don't happen to have a scientific calculator. For example, to calculate (5 x 6) + (12 x 2) + (3 x 7), you can do the following: 5 x 6 = (calculator says 30) MS (stores 30 in memory) 12 x 2 = (calculator says 24) M+ (takes 24, adds it to 30, stores result 54 in memory) 3 x 7 = (21) M+ (takes 54, adds 21, stores the result 75) MR (displays the result 75)
What does M mean on a calculator?
Memory. It's the button that saves your current number, and when you press MRC, or Memory ReCall, the number is restored, giving you a great way to add two products if you have a basic calculator, or to do otherwise impossible equations that have many separate parts.
Does solving math problems on a calculator use memory?
Yes, solving math problems on a Scientific calculator does use memory.
