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.
