The MC, M-, M+, and MR Buttons at the Top of a Calculator
I have never used these in my 18 years of life, not have I even learned what they do. See also Math, Unnecessary, Useless.

what do you use mu for but for mrc its pretty useful for cheating you can save values for questions and its even better for a scientific calculator

These are memory functions. Old or simple calculators have a memory register - essentially a second calculator that can handle addition/subtraction only. M+, M-: Add (or subtract) the current value to (or from) the stored value in the memory register. MR : Recall the current memory register value.

Glad I'm not the only one to not know what they mean. But even after learning them, I'm still probably not gonna use them.
