equation

     \begin{equation}
      math formula
     \label{eqno1}
     \end{equation}

The equation environment centers your equation on the page and places the equation number in the right margin.

The `\label` command is required only if you want to use a `\ref` command to refer to the number assigned to this equation.

The Display Math environment gives the same effect without the equation number.
