Math Symbols in HTML

This page explains how to place various mathematical characters into HTML documents. The symbols have been grouped into the following categories:

Operation Symbols
Relation Symbols
Arrows and Brackets
Greek Symbols
Miscellaneous Symbols

INTRODUCTION
There are several ways to add these symbols to your pages. I will omit consideration of symbols which appear on the keyboard unless, like &, they have a special HTML meaning. Of course, for any symbol, a .gif image can be created and the image displayed using the <img> tag. I will omit consideration of this strategy as well. In the tables below three codes will be given fordisplaying a character: the HTML numerical code, a code that can be placed between a FONT FACE tag, and a special HTML literal code (where available).

Well, how do you use this stuff? The following samples illustrate the useof each code method. To place a symbol in an HTML page or an email message (readable using a web browser) copy and paste the appropriate code into the file (or message) where you want the symbol.
HTML NUMERIC CODE example: to make a left curly bracket {, type &#123;.
FONT FACE TAG example: to write xÎA, type x<FONT FACE="Symbol">&#206;</FONT>A.
HTML LITERAL CODE example: to make a degree symbol °, type &deg;.

One more thing. To form superscripts or subscripts use the <SUP> or <SUB> tags.

SUPERSCRIPT example: to write 2À, type 2<SUP><FONT FACE="Symbol">&#192;</FONT></SUP>.
SUBSCRIPT example: to write x5, type x<SUP>5</SUP>.

WARNING: Sometimes the numeric code for a symbol is the same as used within FONT FACE tags, but sometimes it's different. For example, &#92; produces \ while <FONT FACE="Symbol">&#92;</FONT> produces \. Also, while the codes appear to have become "standard" it is possible that some browser will not support certain characters. This will most likely be a problem when using the FONT FACE method.
