Ive never used these buttons in my life.
How do the mrc m- and m+ buttons work on a very basic calculator?

Discussion Overview
The discussion revolves around the functionality of the MRC, M+, and M- buttons on a basic calculator. Participants explore their uses in storing and recalling numbers, as well as the mechanics of how these buttons interact with the calculator's memory.
Discussion Character
- Technical explanation, Conceptual clarification
Main Points Raised
- Some participants express unfamiliarity with the MRC, M+, and M- buttons on basic calculators.
- One participant suggests that M+ stores the current number displayed, while MRC erases numbers in memory.
- Another participant clarifies that M+ adds the displayed number to memory, M- subtracts from memory, and MRC recalls the stored number.
- A detailed example is provided by a participant illustrating the use of these buttons to manipulate memory, showing how numbers can be added and subtracted from memory and recalled.
- There is a note about the persistence of the stored number in memory until the calculator is turned off or memory functions are used.
Areas of Agreement / Disagreement
Participants generally agree on the basic functions of the M+, M-, and MRC buttons, but there is some uncertainty regarding their usage and the extent of their functionality.
Contextual Notes
Some assumptions about the calculator's memory functions and the specific behavior of the buttons may not be fully explored or defined.

Me either, probably because i don't even know what they are exactly for :/ and on a basic calculator? must have some use to normal math i suppose.

M+ stores the current number shown on the calculator. MRC I believe erases those numbers in memory. I don't use the basic calcs, though since I'm far too accustomed to my scientific one.

huh?
Ok,
m+ adds whatever is on the screen to memory
m- subtracts whatever is on the screen from memory
mrc is the memory recall button which displays whatever is in memory on the screen
here is an example
press mrc
press m-
This makes sure that your memory is clear
Now,
press 5 and then m+ (a small m usually appears somewhere to let you know there is something other than 0 in the memory)
now press mrc, you will see 5
press 4 and then m+
now press mrc and you will see 9 (5+4=9)
press 3 and then press m-
now press mrc and you will see 6 (9-3=6)
remember no matter what else you do, as long as you use no memory functions or switch the calculator off, that 6 will remain in memory.
oh how we love technology
