The Calculator Thread!

Postby Sasha » Thu Sep 25, 2008 1:56 am UTC

(Not really sure if this goes here, but...)
This thread is about calculators, the usually hand-held things people usually use to do maths.
Basically what you like/dislike about calculators, which brand/manufacturer you prefer, what you have/want, RPN v. Algebraic.

For example, I have 4 calculators.
3 HPs: The 48GX, the 11c and the 49g+, listed in order of preference.
1 Pickett Trig Slide Rule. Eeyup, that's an old-school calculator.

So, what do you all have/prefer/dislike?

I own a TI-84 Plus Silver Edition. And it has served me well for..eh...four years now? I love it. I realize saying you have a TI-83/84/89 is not exactly something unique, but mine has lasted from pre-algebra to (now) Calc III. The little rubber pads that are supposed to keep it still are gone, and some buttons are starting to rapidly lose their ink. I'm waiting for the day when I'm able to operate it entirely based on memory because the buttons aren't labeled anymore.

...There's something very wrong with the emotions I have for that thing.

I have a Ti-83 plus. the most basic of basic, but its pretty good. It taught me programming and I played millions of games on it, and have used it for maybe this is the fourth year?

I like it. :)

An HP 49. But it's impossible to type on that as fast as on a TI-84.

I bought a TI-36x Solar for $15 and it lasted about 6 years. Great for its price. Base conversion, fractions, exponents, trigonometry, all that fun stuff, purely solar.

I replaced it with a TI-83 because I was told I needed one for math class. Absolutely had to be a TI-83. (No wonder such ancient technology still runs $100+. lolmonopoly) I'm sure you all know what those are like.

Ahaha, yeah, believe it or not, that calculator was where I wrote what could be called my first piece of code, back in like 7th grade or something. Good times. ^^

Currently use a TI-30xIIB, because that is what my school requires.

I like the 89's pretty print format, and how it lets you scroll through the last 99 calculations.

What?! I know one of my maths teachers hates them. But I don't (hence me having two). I think they're the greatest calculator ever. I wish I could get a non-CAS one though.

Woo! TI-30xIIB for the win! I have the white one. There's a black one as well.
I had the black one but it disappeared, so I got the white one instead.
It's got like, green buttons and shit. Nice.
I don't twist the truth, I just make it complex.

TI-3something solar. It's absolutely wonderful and doesn't require batteries.
TI-89 titanium. It's even more awesome. I'm amazed at it's capabilities and with each class I take I learn more about it's abilities in various subjects. It seems like a bottomless pit of stuff it can do.

Original ti-89 (non titanium). Best thing ever. This little thing let me forget calculus and algebra :P I only go to matlab for calculations if the pretty print scrolls my formulas off the screen and it's reasonably complex.

TI Nspire

both the Nspires i got from winning the "TI team maths challenge" ah that was the most unexpected victory ever. we were invited to the final at their HQ to present the work we had done, after a long evening of playing worms armageddon and drinking alcohol, at just gone midnight we decided we should start thinking about our presentation......
the prizes for winning were awesome, free trip to BETT 2008, and an Nspire CAS. that was a good competition :)

I used to have a TI-85 that I used through high school, college, and most of grad school until I lost it (easily 10+ years). I loved that thing <sniff>. (No, I'm not crying, I just have a cold.)

Now I use windows calculator or whatever calculator I can beg, borrow, or steal from other people in the lab.

You're right. For the HS math i'm doing, however, it's more than sufficient. A TI-89 would be nice, but I think I''ll wait until i have the need for one.
I think the TI-83 is sort of the Honda Civic of calculators. It may not be as great as some, and if you're pro you need something better. But it's crazy popular, and does plenty for most folks.

...QFT. Almost exactly what I would say about mine.

The LRFs are gone from the slide cover, but those on the back are still in good order. And several buttons are unreadable - the plus and minus ones are notable. Also, the custom keypad colour thing (a strange idea, but I would like a black one with a black slide cover if I thought it was worth it) has a couple of cracks in it.

Almost everyone I know has a TI calculator, and everyone else has a Casio.

But that's just the horrible bias against anything but HP speaking. See, I NEED RPN-mode; I was trained on it starting on my dad's HP-42 at about... 3-ish?

I have just downloaded a vista sidebar calculator :Y) pretty awesome feature.
been using that to calculate savings & finance stuff. being Alpha, Im pretty damn proud that I did that. I hate calculating, and I'm shit at it too!
I have a calculator on my phone that I use from time to time too. Mostly for calculating financial stuff. things that most betas could do by heart, admittedly.

I used to own a Ti-83 thingy, back in high school. sold that one for a good price tho.
And my casio before that BROKE TWICE. those damn things were expensive too, not cool :(

TI-83 Plus (from when they first introduced that model. None of this new kid shit with the Titanium and 84) complete with sticky buttons (which require a great deal of force and make a nice satisfying crunch sound to press) on the leftmost column.
TI-89 (Again, from before the Titanium bullshit)
TI-89-83+ (This is a custom kitbash of an 83+'s faceplate onto an 89 in order to defeat idiotic "YOU CAN ONLY USE THIS PARTICULAR MODEL CALCULATOR" rules. Also comes with a TI-83 emulator for those assbag teachers who insist on stealing your calculator and resetting it.)

However I rarely have any of these on me, and usually end up either using calc.exe or running a perl one-liner.

TI-89 Titanium. And yes I love it, even though I hardly use it anymore. The most use it gets is as an integral table when I'm too lazy to look an integral up in a real one (but funny, it's probably more work to type in all the variables and parenthesis carefully than it is to simply flip through a few pages in my integral table). That's because all of my math now is intuitive, the variables are all arbitrary and there's no need to really calculate anything. I love the fact that it does exact answers by default.

I also have a Lutz 252 slide rule that I carry around in my backpack everywhere I go. I really suck at using it, but getting better. But it's only 12 inches and I've discovered that you loose a ton of sig figs on these damn things when they're that short! No wonder everybody went to calculators the moment they were handheld...

I used to have the exact same one, like 4 years ago. From what I remember it can't do very much, never did any graphs or anything on it at least.

Seems like I'm the only one so far to have a TI-82, horrible blue colour. Got one from school for free so I'm not really complaining.

Its just a scientific calculator that "naturally displays forumlae" as you input them. They're pretty much the standard in scientific calculators now I guess.

TI-30XS Multiview does this (hence the 'multiview' bit). And yes, it is sexy. Even sexier, I daresay, because it's a TI.

Middle and High schools love them to pieces because they level the playing field on standardized tests (the metric by which schools are compared and funding decided). Also, the AP tests. In the words of my University math professor: "I taught an AP Calc program this past year. The material seemed to have been chosen strictly because the problems were as hard as possible. I think I went a week without seeing a whole number or basic fraction answer"
