I'm in Pre-Calc H in high school, an my father has been out of work fo a few months, so money is tight. So while everybody has fancy 84s and 89s, I'm stuck with a school issue, really old and slow TI-83. Also, I want to get a computer science/ business degree when I go I college in 2.5 years; both math intensive degrees. Oh and my dream school is MIT haha. So yup I'd love an 89 - besides, I've been reading pstam.com…

Interesting; Many of my calculus classes -- university especially, but also high school -- didn't (don't) allow using a calculator at all on the tests. My university specifically mandates one model of calculator for all students. This model can't do symbolic manipulation/graphing and is not programmable at all. My high school had any sort of graphing calculator banned on tests.

I'm surprised that high schools are allowing students to use this sort of calculator (or for that matter, setting tests where it makes a difference what calculator you have.)

In my high school, a TI-83 was the only graphic calculator allowed on tests, though it was never an issue because very few people had TI-89s.

The AP calculus test is split into a calculator section and a no calculator section, and it definitely helps to have a TI-89.

In college calculus we were only allowed to use a scientific calculator.

you realize by doing this, hacker news will be doing yearly checkups on your grades to make sure their investment is performing well. We won't accept anything less than a top 10 school from US news reports on CS and Business. On the upside, now there's thousands of people who can help you get there.

I'm in Pre-Cal AP at my high school, money's tight and I would love to accept your calculator. The ones they provide at school for free don't have good graphing utilities :/. Anyway, thanks for the consideration, it's nice enough to see someone offer such thing for free. :D Edit: Money's tight at my house, but indraneel24 sounds like he needs it more. Please exclude me from this for his benefit. Thanks!

Thanks man, that really means a lot to me. Its selfless things like this that make me really happy to be alive sometimes :]

No problem! I hope things work out for the best in your road to going to MIT and getting a degree. :)

Today I was trying to smash open a walnut and had nothing hard to do it with. I would appreciate it if you would send me your calculator, as I think it might easily be able to accomplish this.

Aww, come on, what was the point of that? ;)

Just thought it would be nice to have something other than "I'm a working-class high school student."
