Memory Recall and Memory Store are the only ones I know... I dont know what MC and M+ mean.

1) Create a variable, name it something related to 'memory'
2) If the user presses MS then evaluate whats in the textbox or whatever and store that to your variable
3) If the user presses MR then put whats in Memore in the textbox.

I believe thats all there is to those.

MC is Memory Clear so just set the defined variable to 0.
M+ is Add to memory so just add the value to your variable.
