How to use memory in calculator

For some reason I've never known how to use the memory on my calculator. I have the FX-85ES. The buttons are M, M+ and M-. How can I get it to remember a number that I can reuse in later equations and can it remember more than one?

I know about the Ans button but that is useless if you need to use that number in more than one equations later.

M = store current number in memory
M+ = add current number to number in memory
M- = take away number from current number in memory
MRC = recall number from memory

simples

*prays i havent got it the wrong way round for whats being added to what*

But how do you get it to remember more than one number at the same time?

Not all calculators can, some will have multiple memory functions and others won't. In your case I'd suggest looking at the manual as I believe that calculator supports more than one memory function (i.e. as variables) - page E-24 ought to get you started.

Great, that variable A, B, C, D, X, Y looks very useful so it can remember 6 different numbers.
