THIS is the one to get

 

The Casio FX-115 series calculators are allowed on standards boards and Engineering qualifying exams. Of the three such calculator families (TI and HP and Casio), this is the most powerful. And the price is astonishing.

It is easy to confuse the various Casio models. You don't want the FX-115MS. You want this one.

Perfect

 

The natural display function makes it invaluble. It has a table option for doing functions and displaying the range for a certain domain

GREAT CALCULATOR

 

without question, this is the best calculator you could invest in

for $15, you cannot get a better bang-for-buck calculator. as an electrical engineer, the only 2 calculators i use are a 2000 model TI-89, and the Casio 115... it solve simultaneous equations, matrices, polar/rectangular calculations, integrals,...

Not so good

 

Maybe I'm missing something here but it seems that I cant get through 10 chemistry problems without having this thing give me goofy numbers.

2 line screen, pretty easy to figure out

If you enter a string of mixed operations (i.e., 8 x 6 + 2 / 4) it will give you the wrong answer sometimes. I don't know why it can't perform these simple functions without issue.

Does What It's Supposed To

 

The ON/OFF buttons take some getting used to. Otherwise, the calculator is fairly easy to use. The alternate functions are easily identified - for this there is a SHIFT and an ALPHA button designated.

Does what it's supposed to. I mainly bought this calculator for statistics functions. The dual power (solar/battery) is a neat capability and saves me from running out of power during exams. Lightweight (relative to a TI-8X series). Fairly elegant.

Great for Engineering Courses

 

I'm from the "slide rule generation" of engineers, so my preferences are more "no frills" versus what the the younger generation likes. Students love the TI-XX calculators, since they can save crib notes in the memory for exam situations. Not strictly...

Best "bang for the buck" of all calculators for engineering under-grads. I've been teaching various mechanical engineering courses over the last 17 years (under-grad level), and this has been my personal calculator of choice for the last 10 years or...

Not any I can think of. It's a low cost, high value item.

really good stuff

 

if they make this easier to use, and do something about solving equations ( it has a problem with inverses). but apart from that, it is about the best values scientific calculator out there.

- does anything up to 3x3 matrix manipulation - also does vector dot products etc. -does complex numbers - will be able to use this in almost any college class, i have used it through multi-variate calculus (calculus III), and linear circuits. in...

feels cheap, and it is not as intuitive as most other scientific calculators. had to study the manual for almost 1 hour to be able to use this calculator for the same functions that i was able to easily do with other calculators straight out of the box.
