<p>I've been learning how to use it lately and i took a practice test for math 2. I found out that its not all that helpful and doesnt really give anyone an extra advantage. Solving equations are generally faster when you do them by yourself than typing in the calculator. Does anyone disagree and believe it can do a lot more? Im just learning how to use it and not too fimilar with all its functions</p>
<p>I bought one over winter and have mastered the basics. I bought it for Math 2 and for Calc and Stats next year, and college,etc…</p>
<p>So far… I have found it saves a lot of time with options like solve, zeros, matrix, det,etc…</p>
<p>After I finish Barron’s and take a practice test I can fully access how much it helps.</p>
<p>As far as HUGE advantage, nope. My friend took Math 2 with a scientific calculator and got a 800. If you are good at pre-cal, you will be fine. But, you probably will need all the time given.</p>
<p>I found that the TI-89 saves a lot of time in discrete math and calculus; however, for most of the calculus tests we were not allowed to use a calculator. One thing I don’t like about it is that if you are missing one parenthesis it won’t give you an answer or tell you what you are missing (or at least from my experiences) which can be annoying during a test.</p>

<p>Well zeros can be solve with ti 83 with graphing , but i wont argue about matrix and det, but are those the only things they are useful for?</p>

<p>Fortunately this has been fixed by the introduction of the TI-NSpire</p>
