The "Element of with Overbar" Symbol (⋶)

The ⋶ symbol visually represents the "element of" symbol (⋶) with an overbar or line placed above it. This essentially negates the symbol.

Visual Representation

It visually appears like the "element of" symbol (∈) but with an overline or bar placed right above it. This bar typically indicates negation in the context of set membership.

Meaning and Usage

This symbol signifies "not an element of" or the negation of set membership. If \( x \) is not a member of set \( A \), then it is denoted as \( x ⋶ A \).

Comparison to Other Symbols

The more standard and commonly used symbol for "not an element of" is \( \notin \). However, in some contexts or notations, the ⋶ might be used for specific reasons or to convey a nuanced meaning.

Representation in Other Contexts

In LaTeX, the direct command for the typical "not an element of" symbol is \notin. As for ⋶, it may not have a direct command since it isn't as common, and you might need to combine or overlay symbols to recreate it if necessary.

Conclusion

The ⋶ symbol, like many mathematical symbols, should be understood in context. If you're reading a mathematical text and this symbol appears, make sure to refer to the definitions or explanations provided by the author. This is especially true for symbols that aren't universally standard, as their meanings can sometimes be unique to a particular text or context.

Codes for the ⋶ Symbol

The Symbol
Alt CodeAlt 8950
HTML Code⋶
HTML Entity⋶
CSS Code\22F6
Hex Code⋶
UnicodeU+22F6

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 8950. 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: &#8950;</b>My symbol: ⋶

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

HTML TextOutput
<b>My symbol: &notinvc;</b>My symbol: ⋶

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

CSS and HTML TextOutput
<style>
span:after {
content: "\22F6";}
</style>
<span>My symbol:</span>
My symbol: ⋶

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

HTML TextOutput
<b>My symbol: &#x22F6;</b>My symbol: ⋶
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22F6 to place the ⋶ symbol on your canvas. For example:
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+22F6. 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
22F6
[Hold down Alt]
[Press x]

(The 22F6 turns into ⋶. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22F6. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22F6"
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.
