<p>Hahahahahahaha!</p>
<p>One thing to remember is that if you're taking the ACT the 89 is not allowed, they do check these things. A friend of mine had to take the ACT without a calc because he failed to read the instructions, an 83, however, is allowed. I really like that the 89 can do symbolic algebra, solve systems of equations involving any number of variables, and graph in 3-D, those are the features I found most useful as I used it my first year. I found it really useful and accurate in physics. If I had used it to add and subtract rather than relying on my paper and pencil method, which I have found I have become weak at, I would have gotten a perfect score on the mid-term. I really enjoy using the 89 because it has so many features. Although some of the stuff takes time to get used to a lot of it will come just through playing around with the operating system. If you're like me, it's a new toy and you'll play with it anyway. For me, in high school, it had a lot of features I never touched, but that may change once I hit college and the features I need change. I expect that I will be able to use this calculator for quite a while, hopefully right through grad school.</p>
<p>Get a TI-83!!!!!!! It's easier to use.</p>
<p>Actually a TI-89 is nice because you can see what you typed in..</p>
<p>what do you mean</p>
