<div>Will you have extra calculators in class for us to use for
quizzes and tests. I'm have been trying to find my TI-30 for 3
days now and I haven't had any luck. Didn't want to mess up on
the quiz because of it! </div>

I do not bring extra calculators to class as I expect students to
have their own handy every day. In a rare event that a student's
calculator dies in class I can usually scrounge around in my
office and come up with a working calculator -- but you aren't
guaranteed that it will be anything like what you are accustomed
to using and you will also lose the time on the quiz or test that
it takes me to go dig around for it.<br>
<br>
Depending on your professional goals and future coursework, here
are some calculators I can recommend. If you have just got to
get through CHM 111/112 and organic then you only need a basic
scientific calculator. The <a

36x Pro</a> came out a couple of years ago, is under $20 at
Walmart, and will do everything you need and more. It's even
solar powered.<br>
<br>
If you are going on in the physical sciences or engineering and
need a very powerful calculator that has 2D/3D graphing, equation
solving, full numerical linear algebra and symbolic calculus, then
I recommend the <a
href="http://www.amazon.com/HP-NW280AA-B1S-Graphing-Calculator/dp/B00CMWCT26">HP
Prime</a> (HP's new flagship and generally around $135) or the <a
href="http://www.amazon.com/gp/product/B000GTPRPS/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1944687662&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B00CMWCT26&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1TM8Z8G9XFZ2QMM887CM">HP
50G</a> (older, and generally found for under $60). The 50G is
not nearly as cool looking as the HP Prime and has a steep
learning curve, but it is regarded by many in the science and
engineering fields as the most powerful calculator on the planet.<br>
<br>
Don't get me wrong -- HP is not paying me to say these things.
Casio, Sharp, and TI make exceptionally good calculators -- the TI
Inspire is amazing -- but they are primarily geared toward
education. I am a scientific computing professional and numbers
that I am asked to compute are often critical to a projects
success. As such I have spent a lot of time over the years
looking at calculators and their internal workings; I have never
been disappointed by my choice in HP calculators. <br>
