HTML Codes for Mathematics

HTML codes to put mathematics characters on your Web page

The following list includes the HTML codes for mathematics characters not in the standard character set. Not all browsers support all the codes, so be sure to test your HTML codes before you use them.

Some Mathematics characters are part of the Unicode character set, so you need to declare that in the head of your documents:

<meta http-equiv=”content-type” content=”text/html;charset=utf-8″ />

This page is for all of the Math Geeks (an affectionate term) out there who try to add equations and math problems on their teacher web pages. Without an online equation editor like this one, it can be a challenge to write equations in HTML.
