FX-991CW Scientific Calculator

Working on math in my spare time. Was looking for a versatile calculator for everyday use until I came across this one. I was impressed by its features; one of the great pluses of this machine is its ability to display equations as they are written on paper, its fraction notation feature, and its ability to utilize ClassPad.net to generate graphs on a computer via QR codes. Other users find navigating its functions a bit awkward but this is overcome by familiarization of operation. This is true with any calculator. Despite its affordability it is light and its build is durable with a textured case preventing it from slipping off your hand. Key layout is intuitive and the keys have the right tactile feel. It would have been great if this calculator was programmable, but then, it would not be priced as it is. I give this machine Five Stars. Indeed, it is very versatile for a scientific calculator.

I purchased this calculator to study for my FE exam, since it is the most functional Casio allowed. They always make a good product, but I must say, this calculator is great! They have a "math" setting for inputs and outputs when doing algebra, and it shows inputs like it's written on the page. No errors here! It will also solve linear combinations, do probabilistic regressions,and even more.
