<p>Which calculator is the best one for architecture at CMU?</p>
<p>Should I get ti-84?</p>
<p>I think you should invest in an TI-89.</p>
<p>I had a TI-83 when I went through my engineering curriculum, many of my friends had a TI-89. I think I hardly ever touched my calculator after sophomore year since, by then, any problem which I couldn’t solve by hand generally needed to be done in Mathematica.</p>
