Scientific Calculator with Graphic Functions - Multiple Modes with Intuitive Interface - Perfect for Students of Beginner and Advanced Courses, High School or College

⭐️⭐️⭐️⭐️⭐️ 🧮 I really like the CATIGA CS-229 — it’s a solid little calculator that manages to feel both beginner-friendly and advanced. The graphing display is super helpful for visualizing equations, and with over 360 functions (fractions, stats, regression, complex numbers, etc.), I feel ready for everything from algebra to calculus. The screen is clear and detailed, the buttons are easy to press, and it handles a lot without getting awkward. 🔋 The design is compact enough to toss in a backpack, and it’s powered by battery and solar—so it works wherever I take it. The reset button in the back is a bonus if it ever acts up. 📚 Great tool for high school or college students, or anyone who wants a dependable calculator that can grow with them. Highly recommend — worth the pick!

Amazing! Does not have sticky buttons we've had it for about a year now and still working great! It was easy to figure everyone out!

Works great. I missed my scientific calculator. This meets my needs.

This calculator is very affordable, which is its biggest plus. It works fine for basic calculations and is a good option if you’re on a budget. However, the way it displays answers is confusing. When working with logs or powers of 10, it doesn’t clearly show the scientific notation. As shown in the attached photo, the power of 10 isn’t obvious, unlike on a basic Texas Instruments calculator that clearly shows ×10ⁿ. It’s usable and inexpensive, but you have to be extra careful reading the answers.

good for value

Came with instruction manual, the pink looks so pretty and has a nice size screen. Seems like it will hold up for many years. It’s worth the price

Kinda confusing to figure out but it was way cheaper than s ti-84 does same things, wish it had a better tutorial, bur your smart you can figure it out

great product but graphing is a little confusing
