The Mathematical Symbol "Superscript Three (³)"

The "Superscript Three" Symbol (³)

The ³ symbol produces a superscript representation of the number 3. It's commonly used in various contexts to denote cubed values, third powers, or references in written content.

Visual Representation

The ³ symbol visually appears as a small, raised number 3. When seen in text, it indicates that the preceding number or entity is raised to the power of three.

Usage in Mathematics

In mathematical terms, if we have a number \(x\), the expression \(x³\) means \(x \times x \times x\). For instance, 2³ represents \(2 \times 2 \times 2\), which equals 8. It's a shorthand way of writing out the cubing of a number.

Usage in Literature

In written content, superscript numbers often serve as footnote or endnote indicators. If an author wants to provide additional context or a citation about a particular point, they might use superscript numbers to guide the reader to the respective notes section. In this context, ³ would indicate the third note or reference.

Typing ³

To render the "Superscript Three" symbol in documents or platforms that support HTML entities, you can use the ³ entity. It's worth noting that the appearance of the symbol may differ slightly depending on the font and platform used. Outside of HTML, some software or applications might have dedicated shortcuts for inserting superscript characters.

How To Insert the ³ Symbol

(Method 1) Copy and paste the symbol.

The easiest way to get the ³ symbol is to copy and paste it into your document.

Bear in mind that this is a UTF-8 encoded character. It must be encoded as UTF-8 at all stages (copying, replacing, editing, pasting), otherwise it will render as random characters or the dreaded �.

(Method 2) Use the "Alt Code."

If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type 179. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

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

HTML TextOutput
<b>My symbol: &#179;</b>My symbol: ³

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

HTML TextOutput
<b>My symbol: &sup3;</b>My symbol: ³

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

CSS and HTML TextOutput
span:after {
content: "\00B3";}
<span>My symbol:</span>
My symbol: ³

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

HTML TextOutput
<b>My symbol: &#x00B3;</b>My symbol: ³
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x00B3 to place the ³ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"E9"
ctx.fillText(String.fromCodePoint(x), 5, 5);


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

The Unicode for ³ is U+00B3. 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:
[Hold down Alt]
[Press x]
(The 00B3 turns into ³. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u00B3. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u00B3"
document.write("My symbol: " + str)
My symbol: ³
