I've always been curious about the ALPHA button on a modern scientific calculator. The buttons it corresponds to are A, B, C, D, E, F, M, X, Y and also Ranint by which are all in red.
I've made calculated attempts to try and play with them and come to a conclusion why they are there, but I have no idea why. Everything either just equates to zero or a 'Syntax Error' pops up.
If so, could someone out there provide a few examples how they work.
Thank you for your attention.
