Digital camera reviews of Casio FX-115MS Plus Scientific Calculator
Digital camera Review: another impressed engineer
Summary: 5 Stars
This thing is a fully functional engineering grade calculator. I purchased this calculator a year ago for taking the Professional Engineering exam (The TI-89 was banned last year) and I figured that I better get use to using it if I were to use it on the test. It was simple to use. It was quick, it was powerful. The linear equation solver was faster to use than the one of the 89 which really impressed me (great for solving electrical circuits).
Overall, I highly recommend this calculator.
It has now become my primary calculator at work.

needed this for my college math class and also plan to be an engineer and this calculator is one of/if not the most advanced calcs you can have for certain engineering certification exams. has lots of nice features and build quality is good...very happy with purchase.Digital camera Review: good caculator
Summary: 5 Stars
i borrowed my friend's caculator for several months and she just used this one.So i bought this casio caculator.It is good.Digital camera Review: got it for PE exam, now I use it every day
Summary: 4 Stars
This was one of the few calculators on the list for the PE exam. It was also the cheapest (I think). I bought it, and started practicing with it at work so I'd be comfortable with it at the exam. It turns out that I love the data entry format. I used HP's RPN for a LONG time and thought it would be difficult to switch, but this makes even more sense because you enter the problem EXACTLY how you would write it on the paper (i.e. square root sign comes BEFORE the number)! I don't even use my trusty old HP now unless I accidentally leave this one at home. I am even thinking about getting a 2nd one so I can have 1 at work and 1 at home to study with (and I've heard that sometimes calculators walk away during lunch hour at PE exams, so it might be good to have a 2nd hiding in my bag).
The only flaws I've found so far are the instruction manual, quick auto power-off and the plastic cover. The manual does not go into enough detail but there are several references available online so, not a huge deal for me. When I get close to the exam, I'll probably print out my favorite and take it with me. The quick power-off (after about 6 minutes) can be frustrating, but I haven't really had a huge problem with it.
The plastic cover is annoying because it snaps on and off instead of slides. I don't know why this bothers me, it just does. Also, it would have been nice if the cover was flat. Instead, it is slightly rounded with "feet" to stabilize it. The feet work great as long as the entire calculator is sitting on a flat surface but if one corner is off, the whole calculator rocks back and forth every time you hit a button. Also, with the cover snapped onto the back, it is kind of uncomfortable to hold in one hand and enter data. With the cover off it is better, but I'm worried I'll loose the cover.
I am definately happy that I purchased this calculator instead of the more expensive HP that was on the PE approved list.
Digital camera Review: great calculator for the price
Summary: 5 Stars
I'm amazed by the features in a $15 calculator. Basically all casual lab calculations I need are handled by this one. Of course it has all of the standard scientific/trig functions, plus a stats mode for mean, std dev, linear regression, etc. What makes it really great is the simultaneous equation solver for 2 or 3 variable linear equations, the quadratic solver, and the cubic (!) solver. Yes, you can solve these analytically pretty easily, but after awhile it gets tedious and you just want the answer.It also lets you enter an equation and solve for any variable without isolating the one you want first, though this is a bit less successful. The numerical integration feature is nice, though the algorithms for these last two aren't as robust as those of the old hp series (eg math error on I(0,1) [sinx/x) dx]). Also does numerical derivatives, fractions and complex numbers, though I have no need for these. The manual is pretty skimpy, but you can't expect much at this price. It's very easy to use and prompts for variables it needs.In summary, makes a great lab calculator, and any calculations it won't handle are probably best done on a computer anyway.
