math

Is a mathematical operator like summation which instead of adding up the generated elements, multiplies them.

Commonly we use the \( \Pi \) symbol to mean product of. The position and interpretation of the fields takes the same form as summation.

For example we can define \( n \) factorial using this new notation.

\begin{align*} \prod^n_ &= 1 \times 2 \times 3 \times \ldots \times n \\

        &= n!

\end{align*}
