* {{cite web |title=In our AP c++ class we are trying to use virtual stacks to devlop a infix to postfix calculator transalator. To study how exactly the infix notation and postfix notation differ we used on of the very old HP calculators. I was wondering that when you worked for HP did you help devlop some postfix calculators? Do you prefer infix notation or postfix? |editor-first=Stephen Gary "Woz" |editor-last=Wozniak |editor-link=Stephen Gary Wozniak |date=2012 |orig-date=2000-02-13 |work=woz.org |department=Letters-General Questions Answered |url=http://archive.woz.org:80/letters/general/57.html |access-date=2023-09-23 |url-status=dead |archive-url=https://web.archive.org/web/20121104143556/http://archive.woz.org:80/letters/general/57.html |archive-date=2012-11-04 |quote=[…] Our marketing department had a card with a monstrous formula to demonstrate how powerful our calculators were and what postfix calculation was capable of. They challenged people to solve it on a slide rule the normal way. Well, we could all solve it on our [[HP calculator]]s but it took a few tries to get the steps accurate enough […] Finally [[Texas Instruments]] introduced an infix 'algebraic entry' scientific calculator. […] We were all […] laughing at the arithmetic entry as being too weak for engineers. […] our big formula challenge […], sure that nobody could ever do it with the TI calculator. A challenge went up for someone to try. After a short silence I said that I'd try. […] My colleagues couldn't believe it. I told them that you just copy the formula from left to right but not one of them could see through their postfix fog. After all, these were the calculator experts of the world. They are well accustomed to thinking ahead and analyzing an expression to come up with the order of steps to take on an HP postfix calculator, and they had to remember which sub-expressions were in what order on the calculator's stack. None of them could do what I had done, forget that they have to be smart. […]}}
