<p>weird... i was under the impression the 83 had auto solve as well... anyway, i'm not saying don't use it for tests... but just for the class you build a general dependency on it, and ur a freakin idiot when there are non calculator sections, and programmer1234* on the calc bc exam, half of it is non calculator, how do u think the people who live by the 89 are gonna fair on that? i'm gonna guess not too well*</p>
<p>My parents had that same problem with me getting "advanced calculators" as well... I believe it went something along the lines of, "When I was your age..." </p>
<p>Hopefully, I won't become calculator-dependent. I don't think buying an 89 will (for sure) make your math skills atrophy (verb?) though. Ultimately, it's up to the owner. However, in some cases (such as stats)... plugging numbers into the same equations over and over again is a major waste of time. Even our teacher prefers that we use a calculator to solve the problems.</p>
<p>The 89 Titanium is shiny... =) (but not literally so yay) The factoring is awesome.</p>
<p>I am too looking to invest in a good calculator, that can last me for the next couple of years. I was thinking about going with the standard 83, but the functions of the 89 sounds so much cooler. Im not sure if it can actually help me though, but I will need one soon (Precalc/Calc next year)</p>
<p>The 89 is worth every penny. I would never use an 83 when an 89 was avaliable. Get rid of the 83 and get an 89 ASAP. It WILL help.</p>
<p>Well it works to my benefit anyway because I have to KNOW how to do the problems before I design a program for it - I advocate time-saving, not dependency. I only mention that you can use the 89 for everything and COULD depend on it because if you are allowed to use it, it essentially can solve anything, if you tell it what to do, correctly.</p>
