I bought a FX-CG50 instead of the more expensive TI calculators with similar functions knowing that I would have to find on my own how to utilize the calculator. EVERYONE knows how to use a TI but rarely do they use a Casio here. This channel has helped me readily recommend my Casio to anyone in need of a calculator because of all the tutorials offered. Thank you!

What if the hint/warning message ask you the represent mode to select?! OR else follow the function to allow you to transfer the answer to other mode to represent!

Try CubeRoot of -8 and see if you get -2.
