<p>i cant decide which 2 to bring along with me.</p>
<p>I have TI 83 plus, TI 84 plus and scientific calculator.</p>
<p>Which ones do you guys use?</p>
<p>Use whichever one your accustomed to. I like my TI 84 SE</p>
<p>TI-84 Plus Silver Edition</p>
<p>I wouldn't suggest a scientific.</p>
<p>I've used the TI30X in the past because it was the only calculator I need for math, but I'm going to use my new TI-84 SE on the ACT tomorrow.</p>
<p>Use a calculator you are familiar with on the ACT. Bringing a calculator you don't know how to use won't help you. Not to mention you don't even need a calculator to do the math test according to ACT.</p>
<p>I find the TI-84+ SE to be the best calculator for it, though any of the TI-83's and TI-84's tend to be good.</p>
<p>The scientific calculators are a bit more suspecting to human error as they do not let you see what you have just entered.</p>
<p>i wouldn't use a scientific calculator, you can't see as much stuff that you've input. truthfully, i don't see a difference between the TI83 and TI84 since they have the same layout and stuff, but i suppose if you use one in school, it'd be better to use that one. personally, i like using my TI89 since i use that in school, but it's not allowed, so i have to use a TI83</p>
