How to Add Math and Currency Symbols to a Web Page

Add math and currency symbols not found on the keyboard using HTML 4.0.

Instructions

Difficulty: Easy

1. Open the page in a text editing program, such as EditPad or Notepad. Place the cursor where the symbol will appear.
2. Use numeric symbols by typing the following: <#> for the pound (number) sign, <%> for the percent sign, <0> for 0 <1> for the number one, <2> for the number two, <3> for the number three, <4> for the number four, <5> for the number five, <6> for the number six, <7> for the number seven, <8> for the number eight and <9> for the number nine.
3. Add mathematical symbols for typing the following: <<> or <> for the equal (=) sign, <>> or <>< for the greater than (>) sign, <<> for the less than (<) sign, <'< for the per thousand (0/00), <&deg;> for the degrees (F or C) sign and <±> for the plus or minus sign.
4. For mathematic fraction symbols, type the following: <¼> for the one-fourth fraction, <½> for the one-half fraction and (¾) for the three-fourths fraction.
5. Currency symbols can be added by typing the following: <$> for the dollar ($) sign, <¢> for the cent sign, <£> for the London pound currency sign, <¤> for the general currency and <¥> for Japanese yen currency symbol.
6. Save the page and open it in a browser to view it. If the code is correctly entered, you will see the symbol; otherwise, you will see the text of what you typed.

Tips & Warnings

• All symbols have a numeric code, while some entities have both a text code and numeric code. For example, the copyright symbol can be either entered as <©> or <©>.
• All entities begin with an ampersand (&) and end with a semi-colon (;).
• Numeric entity codes always begin with an ampersand and a numeric pound (#) symbol.
• Some older browsers will not recognize character entities. Viewers will simply see the code text.
