${x \choose y}=\frac{x!}{y!(x-y)!}$

Knowing this formula will allow you to compute any input for the choose function. Now, let's compute the result.

${7 \choose 6}=\frac{7!}{6!*(7-6)!}$	Let's simplify the denominator first.
$\frac{7!}{6!*(7-6)!}=\frac{7!}{6!}$	In order to simplify this, let's think about it this way...
$\frac{7!}{6!}=\frac{765...1}{\hspace{3mm}65...*1}$	There is a lot that will cancel here.

Compute: 7Chose6

$\begin{array}{|rcll|} \hline && \mathbf{\binom{7}{6}} \\\\ &=& \binom{7}{7-6} \\\\ &=& \binom{7}{1} \\\\ &=& \dfrac{7}{1} \\\\ &\mathbf{=}&\mathbf{ 7 } \\ \hline \end{array}$
