- jqpabc123 4y agoInstead of more calculators, all you really need is just better design. See above.
- jqpabc123 4y agoWhich causes you to then lose what you have typed in the screen already. Then hit [MX] instead. Problem solved with 1 button instead of a whole extra calculator. "Why should a CPU ever need more than 2 registers?" The question in this case is "Why should a calculator only have 2 registers". This approach doesn't scale beyond 2 numbers? Personally, I prefer RPN where I have a whole stack to work with.
- hn_throwaway_99 4y agoWhat is the [MX] button? I don't think I've ever seen that on a calculator. TBH, though, this is still kind of like arguing that people should never need GUIs because you can do everything on the command line. There is a pretty obvious, fundamental difference being able to see everything on the screen at the same time, vs having to remember what you stored in memory (and what calculations went into it). As for RPN, while I agree most people are never taught RPN.
- jqpabc123 4y ago[MX] = Memory Exchange --- Swap display and memory A better, more intuitive solution than any of the above with available screen real estate is a history tape of prior resultants created automatically. Multiple prior resultants (not just 2) always available to view --- no action required. To recall a number from the tape into the active accumulator for further manipulation, simply click the number. To remove a number from the tape, click and drag right or left. To reorder, click and drag up or down.
