See Modular Arithmetic
\binom{9}{3} produces 9 choose 3.
{n}\choose{r} produces n choose r.
x^{y} produces x to the power of y.
x_{y} produces x with y in subscript.

Also note that you do not have to use braces, "{" and "}", when you only want one character in the operation.
Examples
- x^y is the same as x^{y}.
- x_y is the same as x_{y}.
- BUT x^10 is not the same as x^{10}.
instead of
.
