calculators

i'm looking to buy a new calculator soon, and have been looking at the TI Voyage 200 .

has anyone used this? and would it be banned in my classes?

can you recommend another calculator?

Dude - get a real calculator - HP
[/nerd mode]

That one looks like it could be banned in some classes - aren't there some that don't allow keyboards so you don't copy the tests and the professor can use the same test year after year?

Hewlett Packard...

Unique (I know that by saying this someone will soon dispute me) in that they use RPN, aka Reverse Polish Notation. Sort of awkward to use at first, but once you get the hang of it, you will swear by RPN.

It goes like this.

On most calculators, to do something like 2+2, you hit "2", "+", "2" and "="

On an RPN calculator, you do it this way: "2","Enter","2" and "+".

It doesn't save time for short calculations like that, but for formulas like this:

Mu=0.9(As fy)(d-a/2)

it saves a lot of time and effort because you don't have to use the memory function. You put in the numbers you need and it stores them (usually 4 lines visible) and you can do the operations as needed. Sort of hard to explain, and I'm no good at explaining things anyway.

(I know, I know, TI's have multiple line displays now too - I just don't know how to use them anymore.)

Bonus points for anyone who can identify the above formula.

I agree, the HP is probably the best. I use it for everything EXCEPT graphing (I used the ti83 for graphing in calc classes, but i don't need graphing capabilities much anymore). I would not get the fat keyboard calculators if I were you. The keyboards on those suck anyways. Good notes can only be taken by hand, in my opinion (i guess it depends on what classes you take though).

i personally like to use the TI-83 plus silver edition. but if you don't need the graphing functions just get a standard scientific calc. no need to speend the money on something that you are not ever going to use once you get out of school

I still love my TI-86. I will say, however, that TI makes some of the toughest calculators you can buy. I know this from experience. I've done everything short of running over it with my truck, and it still works perfectly.

*me slaps all those who said casio and/or hp*


TI is a great brand, and although I don't know much about the voyage, I can tell you that there's a 95% chance that you won't be able to use it. Their 8x series are just great. I own an 83 Plus and I have also worked a little w/ 89, both great calculators.

Does anyone here make any TI calc programs besides me? No? *wallows in his calculator nerdiness*

I've made few basic programs for my TI-86, they can be found here. At this moment all programs are in Finnish so they're not very usable for you. TI-86 has been in very hard use, calculating at school and real mobile gaming.

i'm a maths student, and i have only once needed something more than windows calculator... and that was because there's no binomial coefficient button, and i was too lazy to compute it myself.

in most courses you're not allowed a calculator in exams which have a full keyboard (QWERTY or otherwise)... graph calculators with letters on the symbols are fine. the one you linked to has a full keyboard, so won't be allowed.

to be fair, the only thing i ever found a graphics calculator useful for is playing snake.

yeah, plus you can play snake on them

i don't have a graphing calculator though. i've got an old casio digits only one... does everything i need, and more...

graphing calculators are a bit pointless for graphs unless you really have to sketch them in an exam... which, in university maths, they're all to complex to do in a calculator or do in an exam anyway. as for outside of exams, what you really want is Maple.

I've got to agree about the graphing function - total waste. Never used it.

/me laughs at dollerspark for the misplaced devotion to TI

Yup :-) though i havent done more than displaying a graph after asking for a couple of variables

Im at 11th (or 12th, dunno about the american system) and we use graphs like 90% of the time... and we have to sketch graphs a lot at assignments...

T-83 plus seems to be a good choice. Has all the important functions of a graphing calculator, but simple enough for most people to use.

I have an oldschool TI-82. I think we also have a TI-83 and a TI-85 that we got for free because people left them at the library, and Chris asked if he could have them if the people never claimed them. So they held them for him, and after like a month or so, they gave them to him

All three are very good. You'll find stuff that's good about TI's and HP's, it all depends on which one feels better to you. Neither is really better than the other.

Most schools don't allow keyboards, and you ABSOLUTELY can't use them on SAT's and ACT's and tests like that.

I mostly used my calculator to play Golf Got pretty good at it, too... knocked a couple swings off after a few months lol.

agreed. Take a TI-89 and pop the clear plastic border around the screen off and replace it with one from a TI-83 PLUS and you can get away with using it in most any class. Also somone once wrote a fake memory clear program for it that looks JUST like the TI-83 PLUS version, so you can truly fake out the teachers.

As he traveled to a far off land, he found he wasn't traveling alone, but that he had gained companions, and when they found their new land, they started work on a new temple, one that would be OPEN to all who wanted to worship.

It has a "qwerty' keyboard which makes it banned in 99% of [high] schools and on all standardized tests. TI-83+ Silver rox, gotta love ztetris and phoenix.

Personally I suggest a TI-89 or a Ti-86, The 89 hasn't been banned from my classes, my Teacher just erased the memory before the end of course exam to make sure i didn't have any games on it, or saved stuff. They're great calculators though, almost all Texas Instruments, and they can do some really complex shiZnit. Pick one up for about $150 at walmart.

HP12C

HP12C is a classic. It has a lot of financial functions students don't need. But it uses postfix (or polish notation), which enables you to do calculations very fast and without parenthesis. of course, you need to learn to use the postfix notation and get used to it.
normally, 2+3, the plus is between 2 and 3. but in postfix it becomes 2 3 + the plus (or operation) comes at the end, thus postfix.
so you enter 2 first, then 3, then +, to get 5.

At the university I attended we weren't allowed to use calculators at all in our math courses. In our engineering and science courses they didn't care what we used since we had to show our work and they were either open book or had a formula sheet attached. And in case anyone cares I have a TI-85, and most of the student population that I knew of had a TI of some sorts.

Look at my early post up top, it explains RPN a bit better (IMHO)

23
enter
1
+

My fav calc was the Casio fx-5 I was only nine and not many had calculators in those days 1983 (??) and it was one of the first scientific ones and it did fractions.

Confused my teacher no end by seemingly doing really complex fractions in my head.
