I think I know where these errors come from. Older Pentium processors had a bug in the floating-point unit so nobody wanted to have them. That's why Casio bought all of them and put them into their calculators.

It would be great! Casio calc with standard CPU, even faulty! To be serious, there are two reasons why I bought TI89 instead Casio 9850 or 9970 / HP 48

- Great symbolic manipulation. I always liked program Derive.
- Standard CPU and machine code programming that makes it good general purpose machine.

My old Casio Fx-8000 I still use for Hex/Dec conversion, because it is easier for this purpose.

Hah! Only they decided that the pentium cpu's were to good, so they slowed them down so much that a 6MHz Z80 is faster. Hah-hah!

It's all those lines of code to graph y=x+2

What do you guys think of this calculator:

If nothing else, at least it _looks_ better than Casio's other calcs... :-)

my math teacher has one of those; it's only good for basic algebra (at least thats what her son tells me, I've never tried using it's CAS)

I just took the Virginia Standardized "Flanagan" Test (Some new test). They took away the 83's and 89's, and gave us some no-name calculator with something education. I read this article yesterday and I was telling my buddies about it. Truth is, samething happens with the no-name calculators. My science teacher (whose room was the testing area) didn't believe me at first, and then proceeded to do nothing, his motto "tough luck". And then our tests which is supposed to take 2 and a half hours took 15! minutes. To add insult to injury, one of the problem's answer wasn't listed. I say let us keep our TI's.!!!!!!

Hey I live in Virginia too. I'm in 8th grade which means I have to take the F****** Standards Of Learning Tests(SOLs). We get to use school provided TI-83s =). One thing funny that happened though is when we were doing an "official algebra SOL review" (I'm in geometry) the second question didn't even have the correct answer listed! So no matter what you got it wrong. Stupid test makers. Stupid people who SOMEHOW fail the SOLs.

aye, don't get me started on those SOLs... :P

Yea Casio calcs suck donky balls! They probably can't solve 1+1.
