This page demonstrates the default MathEX editing palettes inside a web page.

To create an equation, click on the blue box and begin typing. You can enter the standard arithmetic operations using the +, -, *, / keys, relations using the =, >, and < keys, and powers using the ^ key. The buttons reveal floating palettes that you can click on to access additional notation. Right-click on the equation (Alt-click for Macintosh users) to access context menus, and to see the Content and Presentation MathML for the equation. Use the arrow keys to navigate or to extend a selection.
