How To Insert a Mathematics Symbol

The easiest way to insert a Mathematics symbol is to copy and paste the one you need from the list below. If you're using a Microsoft Office program (e.g., Word or PowerPoint), you can also use the "Alt Code" method.

Here is an explanation of how to insert the "plus minus" symbol (±).

(Method 1) Copy and paste the symbol.

Click on the Mathematics symbol you need from the list below. Press the "Copy" button, and then paste the symbol into your document. Here is the ± symbol as an example:

±

Alt 0177

\00B1

±

U+00B1

Plus minus symbol

(Method 2) Use the "Alt Code."

Every Mathematics symbol has an Alt Code. The Alt Code for the "plus minus" symbol above is 0177. If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type of the number. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

More Methods for Inserting a Mathematics Symbol

(Method 3) Use the HTML Decimal Code (for webpages).

HTML TextOutput
The result is 5 &#177; 1.The result is 5 ± 1.

(Method 4) Use the HTML Entity Code (for webpages).

HTML TextOutput
The result is 5 &plusmn; 1.The result is 5 ± 1.

(Method 5) Use the CSS Code (for webpages).

CSS and HTML TextOutput
<style>
span:after {
content: "\00B1";}
</style>
<span>My sign: </span>
My sign: ±

(Method 6) Use the HTML Hex Code (for webpages).

HTML TextOutput
My sign: &#xB1;My sign: ±

(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).

The Unicode for ± is U+00B1. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:
TypeOutput
B1
[Hold down Alt]
[Press x]
±
(The B1 turns into ±. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u00B1. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u00B1"
document.write("My symbol: " + str)
My symbol: ±
To see the formats for C, C++, Java, Perl, and Python, click on the symbol you need from the list below and follow the link.

(Method 8) Use an Image (for various).

HTML TextOutput
<img src = "myImg.png"/>±
Click on the Mathematics symbol you need from the list of Mathematics below and follow the link at the bottom of the details box. On the new page, there is a widget for creating images of the Mathematics symbol in different sizes and fonts.

See the page for the ± symbol.
