Directive for displayed math (math that takes the whole line for itself).

The directive supports multiple equations, which should be separated by a blank line:

.. math::

(a + b)^2 = a^2 + 2ab + b^2 (a - b)^2 = a^2 - 2ab + b^2

In addition, each single equation is set within a split environment, which means that you can have multiple aligned lines in an equation, aligned at & and separated by \\:

.. math::

(a + b)^2 &= (a + b)(a + b) \

&= a^2 + 2ab + b^2

For more details, look into the documentation of the AmSMath LaTeX package.

When the math is only one line of text, it can also be given as a directive argument:

(a + b)² = a² + 2ab + b²

$$Normally, equations are not numbered. If you want your equation to get a number, use the ``label`` option. When given, it selects a label for the equation, by which it can be cross-referenced, and causes an equation number to be issued. See :role:`eqref` for an example. The numbering style depends on the output format.$$

$$There is also an option ``nowrap`` that prevents any wrapping of the given math in a math environment. When you give this option, you must make sure yourself that the math is properly set up. For example::$$

$$\begin{aligned} \begin{eqnarray} y & = & ax^2 + bx + c \\\ f(x) & = & x^2 + 2xy + y^2 \end{eqnarray} \end{aligned}$$
