Recommendations for RPN Calculators?
sg3000 asks: "My trusty old HP 48S graphing calculator, that served me since engineering school, seems to be giving up the ghost. I haven't used it in a few years, but recently I put new batteries in it. It works, but it makes a loud static/white noise sound when it's on. The noise is not as noticeable when I hold it, but when I set it down on a hard surface, it's really loud. Then it sucks the batteries down incredibly fast (I put new batteries in it, and two days later, they were drained). Any suggestions on what I should buy as a replacement?"
"I'm in graduate school now, and since I'm taking an accounting course, where they don't want us digging out our laptops during a test, I need to buy another calculator. I'm a big fan of reverse polish notation (RPN), so I'd prefer to get another HP calculator.
Do companies still make calculators? I'd love to get another HP 48, but I'm not even sure if HP even makes calculators like that any longer -- on their web site, they're all cheapo-looking single line deals. I've read about something called an HP 48g, but HP has nothing about it on their web site."
i've got a ti-89 and i can't complain, it's hands down the best graphing calculator i've used. It's fairly easy to use but also has tons of features that will keep you busy for months figuring them out. there are many applications you can download for it with the USB graph link as well
Not true, its reverse polish, not un-polish. What if what makes up polishness is the metaphysical equivalent of a palindrome?

WHO ATE MY BREAKFAST PANTS?
But I have to tell this story. My mother, who's being using office machine since FDR's day, learned to use pre-electronic calculators, with purely mechanical logic. For obvious reasons, these were all RPN. (If you can call simple strings of very basic arithmetic functions "notation".) When she got her first electronic calculator, I had to explain to her what algebraic notation was!
