Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.

Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!

The interface on my TI-Nspire resembles the PIM thing that came with Tandy 1000s. The only difference is that it has a thumb-controlled mouse thingy.

Look at my thingsDidn't use it once in my entire college career.

"DURRRRP, THIS IS REQUIRED CALCULATOR, GO BUY IT RIGHT NOW. Oh, but we aren't going to require you to

useit, we just want you to buy it from our bookstore. Thanks."Also, I basically taught myself how to program by using the macro-editor of my TI83. So for me, my $90 calculator led me down a rewarding career path. YMMV.

Except that graphing calculators seem to be one of the few markets where electronics are only going down at the rate of inflation. Especially in the digital/computing world. I remember spending like $1200 for a mid- to low-end computer and monitor in 1992 or so. Nowadays a mid- to low-end computer and monitor will run you more like $600-$800. Or less. And be about seventeen

thousandtimes as powerful.The idea that what is essentially a small computer only dropping in price at the rate of inflation is

absurd.EDIT: Alternately compare a $500 computer from 2004 to a $500 computer now. Then do the same for a $150 graphing calculator. See the difference?

I graduated HS in 1990, up to that point, we were taught to do EVERYTHING even related to math without a calculator of any type. They were strictly forbidden in all math classes and in HS Physics.

I get to college, freshman year I have a Calc class and, as the

ONLYstudent with no calculator in sight, I walk away from it with a solid B... One of the highest for my particular group of students. To this day I still don't own a calculator and when my kids ask me for help with their math classes, I arrive at the answer in my head before showing them how it's done.Writing out answers may take forever, but it can't be beat for understanding the mechanics of how it all works.

This is how things

shouldbe. I became way too dependent on the calculators we were told to use throughout my young schooling, and totally regret it, cause now I have a very hard time working things out in my head. I'm currently trying to practice mental math, many years after I should have become proficient at it.now, mind you, but back then my beloved TI-82 served as a secret gaming machine.I had a couple of really nice games that I downloaded, printed out, and then manually programmed into the thing. Those were the days.

Everyone should own a gaming calculator at some point in their lives.

I've still got my 48gx, still confuses the hell out of people.

Look at my thingsI guess the upside of doing it by hand is that you have an easily-accessible record if you need to backtrack.

Look at my thingsWell then to be perfectly frank you aren't teaching them the right stuff.

Calculators aren't supposed to be used to do the problem, they are there to speed it up.

Back in high school I did a test that was set in 1970 it took me 15 minutes because I did not need to fuck around with long division and logarithmic tables. A good course built around a graphics calculator should be more involved with the concepts as punching out numbers now means nothing.

Satans..... hints.....

*in my high school calculus class, you could use any calculator you wanted, but you had to show every step of of your work. So a graphing calculator can check your answer, but if you didn't set up the problem properly, you could get the right answer and still recieve no credit for the question.

Same here. Also, at the time I bought it, it didn't seem that overpriced. I mean, we had just gotten color gameboys. Just having a calculator I could type whole formulas in and store more than one number in memory was an absolute godsend. Nowadays, though, you'd think they'd at least bump up the screen resolution/contrast, and add some memory. All that stuff would have

substantiallyimproved the experience of working with my TI-83+, and I just used it for high school math classes.I don't get to use calculators for most of my math classes (and I'm an applied math major, so I have taken lots of math)

But I do use calculators in things like, say, microeconomics or financial economics and maybe a few science classes where math isn't so much the focus and you're only using the calculators on tests to aid with number computations
