+title: MathML
+
+If your browser supports it, MathML elements can be used in TiddlyWiki5 WikiText just like HTML.
+
+For example:
+
+```
+<math>
+<matrix>
+  <matrixrow>
+    <cn> 0 </cn> <cn> 1 </cn> <cn> 0 </cn>
+  </matrixrow>
+  <matrixrow>
+    <cn> 0 </cn> <cn> 0 </cn> <cn> 1 </cn>
+  </matrixrow>
+  <matrixrow>
+    <cn> 1 </cn> <cn> 0 </cn> <cn> 0 </cn>
+  </matrixrow>
+</matrix>
+</math>
+```
+
+Renders as:
+
+<math>
+<matrix>
+  <matrixrow>
+    <cn> 0 </cn> <cn> 1 </cn> <cn> 0 </cn>
+  </matrixrow>
+  <matrixrow>
+    <cn> 0 </cn> <cn> 0 </cn> <cn> 1 </cn>
+  </matrixrow>
+  <matrixrow>
+    <cn> 1 </cn> <cn> 0 </cn> <cn> 0 </cn>
+  </matrixrow>
+</matrix>
+</math>
