  <h2>Inline Math</h2>
  <p>Einstein's famous equation $E = mc^2$ relates energy and mass.</p>
  <p>The quadratic formula gives $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ for any quadratic.</p>
  <p>Euler's identity: $e^{i\pi} + 1 = 0$ is often called the most beautiful equation.</p>
  <p>For a circle of radius $r$, the area is $A = \pi r^2$ and circumference is $C = 2\pi r$.</p>
