    I've used that calculator since middle school. I actually don't use calculators in my math courses anymore, but it works just fine for my other science needs.

    I bought a Sharp Scientific calculator when I started college decades ago. I moved up to programmable types, various HPs with the reverse Polish notation, and fancy graphing ones.

    Now at work I use the very same Sharp I bought so long ago...sigh, first love :!!).

    Nearly all the math I do now doesn't involve numbers.

    My good old circa 1997 TI-89 is always close at hand. On-board unti-aware calculation and symbolic differentiation/integration is a must! Anything more complex than that, and I make a MathCAD sheet.

    TI-89 here as well.

    You'd think they'd have improved these in the last decade... Where's my backlit screen? Come ON.... Features people! It's time for features!

    In all fairness, I would prefer something reliable with a HUGE battery life. Back-lighting comes at a price.

    I am a pretty big fan of this little gem as well (as I see most here are):

    I hear that the HP's are much better if you can adjust to the "RPN" format (whatever that is). Perhaps I will try it out one day, but as a poor student, I chose to stick with what is reliable and cost effective. My older 89 (from like 1999 or something) broke, and I find that this newer model, though a bit thicker, is much faster at calculations and graphing. It doesn't need to "think" nearly as long.

    My feelings about the TI-89 Titanium:

    I'll always have a soft spot in my heart for my very first calculator - an HP35 I purchased in 1973 for $395. That was a huge amount of money back then but well worth it.

    I was sorely tempted to post a photo of a Curta mechanical calculator. I'd love to get the chance to play with one of those.

    I'm currently quite fond of my TI-84 PSE. Its feet have started falling off, but I'm not one to judge. :biggrin:

    At work (school) I use a TI-84 because most of our students have something similar, and I can show them how to do stuff on it. But I'm really an HP fan, ever since the HP-21 that I bought 36 years ago when I started grad school. On the desk next to me right now, at home, is an HP-11C that I bought probably about 25 years ago. It's still going strong, and I use it for all my calculations at home.

    my first HP calculator when i went to engineering school was the HP-15C (looks like the 11C above). one of the things i really liked about it was the programming was simple, just a recording of keystrokes. my next, was the HP-48SX, but i never really did get into any expansion or programming with it, beyond simple one-off programs. so the same love wasn't quite there with the 48, despite higher utility. i think if it had been about 10X faster and came shipped with a serial cable and software i would have bonded better with it.

    The best calculator ever!

    I like the TI-89s but really I rarely use it and when I do I could just use the one that I have downloaded onto my computer.

    The calculator I use all the time is a casio fx-991MS


    I can do everything I need to on it and what made me originally love it was that it solves any polynomial. In grade 11 and 12 it saved my butt a couple times when I was using it to check my final answers (is that cheating?? haha)

    I'm really happy with my Casio ClassPad. The 2D math feature is so user friendly. I so wish the screen was brighter though.

    I have TI-84 Plus now, I think it's awesome, before i had TI-82 and
    I don't see much of a different exept faster CPU in TI-84.

    No symbolic integrals and equation solver but thats always more easy to do by hand i think.

    I considered the 15C, but I finally decided that for the kinds of calculations I did (and still do), complex numbers, matrices, and numerical integration weren't worth the higher price, so I went with the 11C.

    Last summer I found a good deal on a HP 50g at Best Buy and bought one, but I haven't really had the time to teach myself how to use it effectively yet. The 11C is still my workhorse at home.

    I have open office and use the calc built into the software when using the spreadsheet function

    You're only saying that because you haven't tried it. :-p

    Real men don't use calculators.
  25. Aug 3, 2011 #24
    Hehe, I have tried it, just like using a pen :)
  26. Aug 3, 2011 #25
    You're right. Real men don't do maths at all, in fact. Real men play rugby, lift weights, and dig ditches for a living. Or work construction, where they eyeball their measurements.

    That's what I think of when I hear the term "real men" anyway. I don't think of some nerd in his basement with a table of integrals looking things up manually. :-p
