<p>It stuns me that this calculator are allowed on the SAT's. There is no more actually having to solve algebraic equations, only typing into your calculator and watching it solve for you. Major time-saver in any math class, and I think simply having and using one on the SAT's can improve your math section score, as a time-saver and being more precise on your answers.</p>
<p>The math is really easy on the SAT, and by easy I mean really really easy. The challenge comes from the questions themselves and how they are written. You can't just use a calculator to logic your way out of some of the problems, they require good numerical reasoning skills.</p>
<p>calculators suck-----they only slow you down.</p>
<p>caa5042 has it. sat math is way too trivial to waste time inputting stuff into the calculator. the 89's real use is to play some phoenix after you finish :)</p>
<p>the ti-89's real strength comes in doing complicated, tedious calculations (e.g. ugly integrals, matrix decomposition, big taylor expansions -- stuff you would never need in an sat)</p>
<p>Well, the TI-83 has a solver too, you really should never need something like the quadratic formula on the SAT if you've got a good calculator.</p>
<p>I like my ti-83 for the graphing problem... quadreg!!!! make me my parabola... boom 3 and 7 thanks!!!</p>
<p>haha anyone remember that question on the june SAT?</p>
<p>A TI-89 is very helpful for AP Calculus.
It will do a lot of tedious integrals and derivatives that would otherwise take a while.</p>
<p>SAT Math is easy, but I, personally, tend to screw up a bit, and I bet a lot of people also do, and anything that helps you think less is useful in a 4 hour test. </p>
<p>Also, yeah, you kinda need a TI-89 for AP Calculus. I can't imagine not having one on the test at the end.</p>
