+# Math Support in Markdown
+
+This page demonstrates how to use math expressions in Markdown.
+
+## Inline Math
+
+- Einstein's famous equation: $E = mc^2$
+- The Pythagorean theorem: $a^2 + b^2 = c^2$
+- A simple fraction: $\frac{1}{2}$
+
+## Display Math
+
+The quadratic formula:
+
+$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
+
+Maxwell's Equations:
+
+$$
+\begin{align}
+\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
+\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
+\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
+\nabla \cdot \vec{\mathbf{B}} & = 0
+\end{align}
+$$
+
+A matrix:
+
+$$
+\begin{pmatrix}
+a & b & c \\
+d & e & f \\
+g & h & i
+\end{pmatrix}
+$$
+
+## Usage Instructions
+
+You can write math expressions in your Markdown files using:
+
+1. Inline math: `$...$` or `\(...\)`
+2. Display math: `$$...$$` or `\[...\]`
+
+For example, to write Einstein's equation inline, type `$E = mc^2$`.
+
+For a block equation like the quadratic formula, use:
+
+```
+$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
+```
