What is the MathJax code for an index notation (n over k)

What is the MathJax code required to properly format an index notation for Pascal's Pyramid like so: N over K

The cheatsheet here at MetaStackoverflow has not yielded me results.

Solution

  • You can use a simple matrix.

    \begin{pmatrix}
   n \\
   k
\end{pmatrix}

    This will generate the wanted result.
