The Mathematical Symbol "Circled Division Slash (⊘)"

The ⊘ Symbol in Mathematics: Circled Division Slash

Mathematics, with its vast array of symbols, often presents unique and lesser-known notations that have specific applications. One such symbol is the ⊘, referred to as the "Circled Division Slash". This article endeavors to shed light on its significance, underpinned by pertinent examples.


The ⊘ symbol is not as commonly used as basic arithmetic symbols, but it can represent specialized operations or concepts in specific areas of mathematics or technical fields. Essentially, it combines the notion of a circle (or circled operation) with a division slash, potentially signifying a variant or related division operation.


  • Example 1: In certain mathematical contexts, a circled operation might indicate a modular operation. If used in this way:
    \( a ⊘ b \)
    could represent \( a \) divided by \( b \) under some modular arithmetic or specific algebraic structure.
  • Example 2: In technical or engineering applications, ⊘ might be employed to represent a specific, standardized operation or process related to division or splitting.

While the ⊘ symbol is not as prevalent in everyday mathematical notation, its presence in specialized contexts underscores the diversity and richness of mathematical symbols. Understanding such notations is pivotal when delving into niche areas or advanced studies.

How To Insert the ⊘ Symbol

(Method 1) Copy and paste the symbol.

The easiest way to get the ⊘ 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 8856. 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: &#8856;</b>My symbol: ⊘

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

HTML TextOutput
<b>My symbol: &osol;</b>My symbol: ⊘

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

CSS and HTML TextOutput
span:after {
content: "\2298";}
<span>My symbol:</span>
My symbol: ⊘

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

HTML TextOutput
<b>My symbol: &#x2298;</b>My symbol: ⊘
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2298 to place the ⊘ 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 ⊘ is U+2298. 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 2298 turns into ⊘. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u2298. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u2298"
document.write("My symbol: " + str)
My symbol: ⊘
