<p>So I'm planning on majoring in Computer Engineering with pre-med track this fall at UCSB.</p>
<p>I used a TI-83+ Silver all through high school... I lost it around May and now need a new calculator.</p>
<p>So do I go with 84's or 89's?
or nspire or nspire CAS...</p>
<p>I read on here that sometimes exams/professors do not allow 89, so an 84 would be better than nothing, but I'm not planning on buying two calculators.</p>
<p>I checked professor's websites for previous years of math courses...
and all my math classes (3b, 3c, 5a) don't allow any calculator on exams so the 89/84 problem doesn't exist.</p>
<p>But, for other computer engineering/premed courses, which will be more beneficial, 84 or 89?</p>
<p>If the nspire CAS could also have that 84-keyboard attachment, that would be the best... but it doesn't, so nspire doesn't seem that useful to me
it seems that nspire = 84+
and nspire cas = 89
except both have a more defined screen...</p>
