Other Mathematical Notation
Mathematica supports an extremely wide range of mathematical notation, although often it does not assign a predefined meaning to it. Thus, for example, you can enter an expression such as , but Mathematica will not initially make any assumption about what you mean by .
is an operator, but it does not initially assign any specific meaning to it.
This gives Mathematica

There are some forms which look like characters on a standard keyboard, but which are interpreted in a different way by Mathematica. Thus, for example, or Esc displays as \ but is not interpreted in the same way as a \ typed directly on the keyboard.
characters used here are different from the \ and ^ you would type directly on a keyboard.
Most operators work like and go in between their operands. But some operators can go in other places. Thus, for example, Esc and Esc or and are effectively operators which go around their operand.
The elements of the angle bracket operator go around their operand.

You can use letters and letter-like forms anywhere in symbol names.
