    • Perfect for homework, tests, and standardized exams
Great reliable calculator for high school students. The Texas Instruments TI-84 Plus Graphing Calculator is easy to use, durable, and handles everything from basic algebra to advanced functions without issues. I bought two of them for both my high schoolers, and it’s been a solid investment—perfect for homework, tests, and standardized exams. The layout is a bit old-school, but it’s very practical and gets the job done every time. ... show more

    • This is an amazing calculator
When I was much younger I had one of these for high school because they were mandatory, however as I got older I lost the one I had and had to purchase another one for a college math class, while using this calculator in that class I discovered features and functions I never thought imaginable and it really helped me pass my class, thanks !✅👍 ... show more

    • Just buy this for your High schooler.
I have two sons, one has just graduated high school and another one is now sophomore. By experiencing with my older son, this calculator is like essential for student to prepare Sat math as well as school math class. And my older son continually uses it in his college math classes of course. So I bought another one for my younger one. Highly recommend. ... show more

    • Complicated/large learning curve
This calculator did what it needs to do for the class that my son was taking, but the functions could’ve been laid out better and easier to access . It took my son about a week to really learn how to use it and he still runs into some problems trying to use it for some of the math questions just because the functions are counter intuitive and hidden behind the function key menus. If I would’ve known how much of a learning curve it was to use I probably would’ve had him continue using the online calculators that he was using prior to getting to this calculator because it was easier to get to the functions that you needed. Once you learn how to navigate the calculator it does what it needs to do and is a powerful tool you just have to take the time to learn the ends and outs. If the instructions and the functions were easier to use this calculator would definitely be five stars but because of the problems my son had in learning how to use it I could only give it a four star rating. ... show more

    • Worth the money !
It came with various things making it worth the money! The only thing that was weird was that the case had pencil markings on it like if it had been used. But other then that the calculator is great!
