In the following, the quantity + is the whole radicand, and thus has a vinculum over it: a b + 2 n . {\displaystyle {\sqrt[{n}]{ab+2}}.} In 1637 Descartes was the first to unite the German radical sign √ with the vinculum to create the radical symbol in common use today.
An overline, overscore, or overbar, is a typographical feature of a horizontal line drawn immediately above the text.

[1] [2] The order of the coordinates is significant, and they are sometimes identified by their position in an ordered tuple and sometimes by a letter, as in "the x-coordinate". The coordinates are taken to be real numbers in elementary mathematics , but may be complex numbers or elements of a more abstract system such as a commutative ring .
