## Questions & Answers

**Q: Could a student use this instead of Ti 85?**
A: There’s a school actually still asking for TI 85s as of a year ago? Anyway this is more comparable to a ti 81 or ti 80 (using close to 30 year old calculators as I’m in shock to see someone asking about a ti 85

**Q: Is this calculator the same as a TI-83/84 calculator?**
A: A couple of weak points from my perspective.  The 1/x function requires two button presses - I use that all the time for chained calculations in chemistry, so dedicated button is a must for me.  Also the RCL is a two button-press operation whereas STO is direct one-press; for me, it should be the other way around because I store often-used constants, like ideal gas constant, avogadro number, etc.,  in memories and need them with single button press.  Button presses matter, especially on tests.

**Q: where is the function button on this CS-183?   for:   X^Y power (example 4^4 = 4x4x4 = 64**
A: I don't know. The instructions for the unit were so bad I ended up giving it to a friend's daughter. I bought a reconditioned TI-89 from Amazon: plenty of YouTube videos for using the TI-89. The unit in question may be a very capable calculator; the included instructions are terrible. No YouTube support.

**Q: How do you find npr along with ncr on this calculator? i bought it a couple weeks ago and i find myself struggling to find the functions .**
A: Yes

⭐️⭐️⭐️⭐️⭐️ 🧮 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!
