<p>I’d ask your math teacher.</p>
<p>At my school you’re screwed if you have an 89, at least for Stats. Our books is from 2001 and our teacher basically only knows how to use 83’s and 84’s… because that’s what the book recommends. My high school recommended TI-83’s when I was in the 8th grade, because that’s the set standard for my high school.</p>
<p>I have an 83 and I love it to death. I can do everything on it in Stats.</p>
