    • Good calculator for college courses.
Color: Pink
I needed a basic calculator for college courses and I haven’t had any issues with it. It works well, it’s easy to use, and the battery is long enough to last more than a year maybe longer, it has for me.

    • I'm still not sure to operate it correctly.
Color: Pink
I took Calculus I as an elective course. I haven't fully mastered the operation of the calculator yet because I have many limit problems, but I can't find the symbols for the limits.

    • Not worth the price
Color: Pink
I had decent expectations with this product when I was looking for a graphing calculator for my college math class. I didn’t want to pay for a higher well known brand so I decided to give this one a try. I paid $39.99 but the calculators quality is poor. The number keys and not firmly in place and keys tend to tilt. Another thing that is super annoying is that you almost cannot read the tiny letters over the numbers while attempting to use other functions. Over all I wasted my time and money and I ended up buying that $160 brand name calculator for my needs. This product will be returned and I would advise you just pay the money for a Texas Instrument brand and avoid the hassle. ... show more
