How To Insert a Mathematics Symbol
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 the number. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)Video Explaining How to Insert Special Symbols
This video explains 7 ways to insert a special symbol into an MS Office application (e.g., Word) or a website using HTML, CSS, or JavaScript:More Methods
There are six more ways to get the Mathematics symbol you need. The other methods are a little more complicated and are typically used by programmers or graphic designers. Methods 3-8 are shown below the list of Mathematics symbols.Mathematics Symbols

More Methods for Inserting a Mathematics Symbol
(Method 3) Use the HTML Decimal Code (for webpages).
HTML Text | Output |
---|---|
The result is 5 ± 1. | The result is 5 ± 1. |
(Method 4) Use the HTML Entity Code (for webpages).
HTML Text | Output |
---|---|
The result is 5 ± 1. | The result is 5 ± 1. |
(Method 5) Use the CSS Code (for webpages).
CSS and HTML Text | Output |
---|---|
<style> span:after { content: "\00B1";} </style> <span>My sign: </span> | My sign: ± |
(Method 6) Use the HTML Hex Code (for webpages).
HTML Text | Output |
---|---|
My sign: ± | 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:Type | Output |
---|---|
B1 [Hold down Alt] [Press x] | ± (The B1 turns into ±. Note that you can omit any leading zeros.) |
JavaScript Text | Output |
---|---|
let str = "\u00B1" document.write("My symbol: " + str) | My symbol: ± |
(Method 8) Use an Image (for various).
HTML Text | Output |
---|---|
<img src = "myImg.png"/> | ± |
See the page for the ± symbol.
