How do the memory keys work?

Memory keys normally work by adding and subtracting values to them. It looks like you have two memories available, memory I and memory II. (M- I M- II M+ I M+ II) You recall these values with the MR(C) keys to use them in other calculations. Finally, you can clear the memory using the MC keys. Sometimes there is not a MC key. In this case, the easiest way to clear the memory is to recall the memory, multiply it by -1, and add it to the memory. This should set it back to zero.

As an example, if we enter 5 M+ I, 10 M+ I, and then hit MR-I, we should get the answer of 15. If we then enter 13 M- I, and hit MR-I, we should now get an answer of 2. Now if we hit MC - I and then MR - I, we should get the answer of 0.

Let me know if you have any questions.

Good luck,

What is MR

On some calculators the "MR" key recalls the number stored in memory (Memory Recall).
The power-raising key is usually marked "^" or "x-superscript-y" or "y-superscript-x".

If you're asking about a particular calculator, what make and model?

What does MC, MR, & MS mean?


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.

How to take off mem cleared

About hearing your question it sounds like you are having problems with memory(the letter M) that is always appears on the screen of your TI-15 Explorer Calculator. So, for you to cancel it you have to press "MR/MC" button twice then finally hit the "clear" button.

hope you get it right...

What does MR, MC,MS & M+ means in a calculator

My best guess would be this ::

MR = Memory Recall

MC = Memory Clear

MS = Memory Store (Store this number in Memory)

M+ = Add this number to the number in Memory

What does MC,MR,M-,M+ on the calculator mean and do?


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!!
