<p>1st-Is one allowed to use a TI-89, and is it worth buying if i have an 83
2d what are the best programs to use for the sat 1 math and if you have the links that would be GRREAAT.</p>
<p>For programs search at <a href="http://www.ticalc.org%5B/url%5D">www.ticalc.org</a></p>
<p>and a TI-83 is good enough...all the questions on the SAT can be solved without a calculator.</p>
<p>I have a TI-84 Silver...that's acceptable. I think you can use a TI-89...but i wouldn't buy it.</p>
<p>Yes TI-89s are allowed, but you definitely don't need one to do well on the math, so no it's not worth it if you already have an 83.</p>
<p>what do you mean by programs?</p>
<p>^ calculator programs..</p>
<p>You can write/download your own programs to use on your calculator.</p>
<p>You shouldn't need any calculator programs on the SAT, because all of the problems really can be solved without a calculator. I only used mine for longer computations and maybe to graph some function I didn't want to think about... but honestly, it's not worth buying an 89 and finding all these programs.</p>
<p>If you are going to take Calculus before you get out of high school, I'd suggest buying an 89 because differentiation and integration are a lot easier on an 89... but if not I wouldn't worry about it because they definately aren't cheap.</p>
<p>Make sure if you do buy an 89 though that you are comfortable with it before you take the test.</p>
