    The highlighted function seems to be the square root but I remember that in iOS 6 it was without the "x" and the "2". Is the highlighted one the square root?

    Try entering 9, and hit the key. If the answer is 3...it's probably the square root key!:p

    ;) :D

    I know, I tried and the answer is 3 but that 2 really confuses me. I use the square root all the time when I take a test at chemistry and I just wanted to make sure.

    Yes. This is mathematically still correct. Most people just don't write the 2 because √ symbol is universally understood to mean the square root (since x^2 is x "squared"). The button next to it is the cube root (x^3 is x "cubed"), and so on.

    Yes that's it! 2 is square root, the one next to it with 3 is cube root, and the one next to that with the x lets you specify what root -- 4, 5, the 99th root, etc.

    In iOS 6 and other calculator apps it's just the "√"

    Ok, now I understood, thanks all of you!
