Seems to work great for the kiddo in his sophomore year of high school

    • Scientific Calculator with Graphic Functions
Color: Black
Bought this for my son's first year of High School. It's is very easy to operate. I had to show him how to use it to do his homework. The battery life is very resilient. This is a very good calculator for the lower price point. There were no other color choices other than black to choose from... but that is completely fine with us (myself & my son). ... show more

    • Flimsy But Works
Color: Pink
The casing is thin, the battery cover broke immediately, just taped it up, i am hoping to get 4 school years out of it, so we will see, the price is very good, pink is popular but if you are buying this for a student under the 9th grade i would say no.

    • Ok
Color: Black
The overall quality is ok. Cover - The calculator cover doesn’t fit. It’s too big. It falls off which renders it useless. Can’t protect the calculator while in bag. Buttons - The buttons are loose and rattle which give it a cheap feel. Display - the display is ok. Directions - the directions towards how to use functions are quick, hasty, and require a lot of trial and error. Price - Great but it gets you marginal quality. Overall - it gets the job done. ... show more

    • A good helper for learning math.
Color: Black
This return is not a product problem I bought the wrong one myself, but the interface of this calculator is as clear as a tutorial, the keys are comfortable, and it is not a matter of effort to knock it out. It is a fact that the calculation speed is amazingly fast, complex operations are solved in seconds, the drawing function is intuitive and clear, and the function image is clear at a glance. ... show more
