Good quality
Color: Pink
Good quality. The color is very cute, and I used it for pre-algebra, algebra, and advanced maths, and it does have other modes for other grades, so this would work for grades 6-12. It has lots of features that are required for highschool, so it's nice. It also came with another simpler scientific calculator with works with basic maths and elementary levels. It was worth the buy and I'd do it again. I gave the graphing calculator to my oldest in middle school now going to high school and the scientific calculator to my youngest that is in elementary.

Best budget graphing calculator
Color: Black
For half the price of The ti-84 plus It can do all things that calculator can do and more.
Let’s start with the design, I really like the design of this calculator. It’s minimalistic, simple, not too distracting but still ha some flair. I like the rose pattern on the back it gives it a nice touch that stands out from other calculators.
For a graphing calculator, It’s easy enough to use of course like with all graphing calculators there is a learning curve. You really need to familiarize with all of the buttons in order to use the calculator properly. I had to look up a lot of YouTube tutorials to get the feel of how the buttons work.
That being said if you do know how to fully use this calculator is very useful. There is a bunch of menus with a lot of features. The notetaking feature is the one I normally use the most. It’s really helpful keeping mathematical equations and formulas for reference later. It really helped me a lot but it comes to test taking. The thing i hate about Texas instruments calculator is when I type in 2xπ, it would just give me 2π without an option to see the decimal answer. This really irritated me as it was something I could’ve easily guessed without a calculator. However with the Casio calculator when I type in the same equation, it gives me a choice to see the decimal answer along side with 2π. In a lot of situations involving pi, this could make or break a problem. I am very glad that Casio allows you to see both answers.
It’s very good value for money. Like I said for half the price of the ti-84 plus, the Casio can do exactly the same things that calculator can do and then some. Great value for money. It’s pretty concerning that Texas instruments has been the the standard calculator in schools and colleges and is required in a lot of classes. Not a lot of people can shell out double the price for the calculator. I hope to see casio being used more in American schools as we need more choice and competition as clearly lack there of.

Really good for Pre-Calc
Color: Black
I’ve had this calculator for around a month and it’s really good. I’m currently in Pre-Calc 2 and this thing is amazing; I haven’t used the graphing feature quite a lot, but it has a bunch of other neat features besides that.
Features that have really helped me is where the calculator gives exact radical (square root) values of trig functions (Ex. sin 60° = √3/2) and giving exact radian values such as pi/6 instead of a decimal. Which was the one thing that made me stop using my TI-84 (other than it was big and slow). It also solves equations up to 6th degree and has a very easy-to-use UI that doesn’t take that long to get used to. Less commonly used functions show up on screen by pressing the F1-F6 keys which is a lot better than the TI’s navigating through 4 different menus.
Overall, it’s a wonderful calculator that has awesome features even if you don’t use it for graphing (which i haven’t been doing very much graphing lately) ESPECIALLY for the price (it goes on sale for ~$50 often)

Might be the best watch… ever.
Possibly the perfect watch. Easy to read display and light. Great functions. Lightweight and comfortable to wear. Tough solar to keep charged and multiband 6 for accurate timekeeping. Love it. Excellent value too!
