CATIGA CS229 Scientific Calculator with Graphics Functions, Multiple Modes with Intuitive User Interface, for Beginner and Advanced Courses

Q: Could a student use this instead of Ti 85?

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 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

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.

A good calculator at a reasonable price.

This is a good product and performs as specified. However the instruction manual is not entirely as it should be. Small improvements will be helpful like some details regarding the mathematical functions and a better formatting and presentation. Should be made suitable for high school , college beginners and those wanting to catch up quickly. That would make the product excellent.
