The big difference seems to be that with RPN you have to memorize which groupings interact with which, and how, to put operations at the right place, whereas with the normal method the machine does it for you if you follow exactly the written equation (with SOMETIMES extra parenthesis to make sure the machine understands correctly). I admit, I never used an RPN calculator before writing this post. For the RPN you forgot to count the ENTERs between values (otherwise 2 8 is 28), and for non-RPN there were too many parenthesis as you said (and the last one can be dropped because = closes it automatically). :)Īctually, it's 19 vs 19 keystrokes, not 14 vs 28. I would imagine a calculator that interprets your input for you would take up far more valuable RAM than many are willing to give it.but then again, you probably need the calculator to figure out just how much RAM it would actually need. It is truly a sad day that people need a calculator for that, but that is for another debate. I believe someone has already said this widget was designed to balance your checkbook. If you want your calculator to do more than that, then pick up a more advanced version. In this instance.the calculator is assuming you are smart enough to recognize the order of operations, and are giving the input accordingly. So the calculator does the math, (in this case =10, and awaits your input for the multiplication) Basically, any time you enter a calculation, 5+5 and then hit the "*" key, it acts as an "=" key before performing your calculation. I believe it works like the old skool CPA calculators (The ones with the little receipt rolls), you have all seen them.Īnyone who has had an advanced math course will be driven batty by them, the way they make you enter complex calcuations.
