The Mathematical Symbol "Element of with Long Horizontal Stroke (⋲)"
The "Element of with Long Horizontal Stroke" Symbol (⋲)
The ⋲ symbol is a less commonly used mathematical notation that may denote the concept of "not an element of" in set theory. However, the standard representation for "not an element of" is typically written as ∈ with a line through it. The specific usage and meaning of ⋲ can vary based on the context in which it's used, and it's essential to refer to the specific definition given in a mathematical text or paper.
Visual Representation
This symbol visually consists of the "element of" symbol (∈) with a long horizontal line (or stroke) going through it.
Common Uses
Given the variability in its use, it's most commonly found in:
- Set Theory: To indicate that a certain element does not belong to a particular set.
- Examples:
- If \( a \) is not an element of set \( B \), then it could be expressed as \( a ⋲ B \).
Representation in Other Contexts
In LaTeX, depending on the package or symbol set you're using, there might not be a direct command for ⋲. However, you can typically represent "not an element of" using `\notin` within a mathematical environment.
Conclusion
The ⋲ symbol serves as a notation to represent the exclusion of an element from a set. Whenever encountering this or similar symbols, it's always crucial to be aware of the specific context and the definitions provided in the relevant mathematical literature or documentation.

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 8946. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)(Method 3) Use the HTML Decimal Code (for webpages).
HTML Text | Output |
---|---|
<b>My symbol: ⋲</b> | My symbol: ⋲ |
(Method 4) Use the HTML Entity Code (for webpages).
HTML Text | Output |
---|---|
<b>My symbol: ⋲</b> | My symbol: ⋲ |
(Method 5) Use the CSS Code (for webpages).
CSS and HTML Text | Output |
---|---|
<style> span:after { content: "\22F2";} </style> <span>My symbol:</span> | My symbol: ⋲ |
(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).
HTML Text | Output |
---|---|
<b>My symbol: ⋲</b> | My symbol: ⋲ |
JavaScript Text |
---|
const x = "0x"+"E9" ctx.fillText(String.fromCodePoint(x), 5, 5); |
Output |
⋲ |
(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).
The Unicode for ⋲ is U+22F2. 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 |
---|---|
22F2 [Hold down Alt] [Press x] | ⋲ (The 22F2 turns into ⋲. Note that you can omit any leading zeros.) |
JavaScript Text | Output |
---|---|
let str = "\u22F2" document.write("My symbol: " + str) | My symbol: ⋲ |

More about Mathematical Symbols
Mathematics is a universal language that is used to describe and understand the intricacies of the universe. At the heart of this language are symbols, concise representations that convey specific meanings and ideas.Just as letters come together to form words in spoken languages, mathematical symbols combine to form expressions and equations, encapsulating intricate ideas in a compact form. The history of these symbols is as varied as their meanings; some have been in use for centuries while others have been introduced more recently to describe new discoveries and concepts. Whether you are a student, educator, researcher, or simply curious, this list of mathematical symbols will serve as a guide, shedding light on their meanings, origins, and applications.
From the simple plus and minus signs to the more esoteric and complex, each symbol has its unique story and significance.
