The Mathematical Symbol "Curly Logical And (⋏)"
The ⋏ Symbol in Mathematics: Curly Logical And
Amidst the myriad of symbols in mathematics and logic, some stand out due to their distinct appearances and specific applications. One such symbol is the ⋏, also referred to as the "Curly Logical And". This article provides insights into its function, accompanied by illustrative examples.
Usage
The ⋏ symbol, characterized by its curly or wavy appearance, represents a nuanced form or variant of the standard logical "AND" operator. While the precise interpretation can vary based on the context, it typically indicates a form of logical conjunction that may carry additional implications or conditions compared to the standard "AND".
Examples
- Example 1: In specific logical systems or frameworks:
\( p ⋏ q \)
This might represent a conjunction where both \( p \) and \( q \) are true but under certain conditions or stipulations distinct from the regular logical "AND". - Example 2: In advanced logical semantics or set theory contexts:
\( A ⋏ B \)
This could denote an intersection operation that meets specific conditions or properties that differentiate it from the conventional intersection.
In essence, the ⋏ symbol, while not as prevalent as the classic logical "AND", plays a unique role in diverse logical contexts, highlighting the intricacies and depth of logical notations. Appreciating these specialized symbols is integral when delving deeper into logic and mathematics.

Codes for the ⋏ Symbol
| The Symbol | ⋏ | |
| Alt Code | Alt 8911 | |
| HTML Code | ⋏ | |
| HTML Entity | ⋏ | |
| CSS Code | \22CF | |
| Hex Code | ⋏ | |
| Unicode | U+22CF |
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 8911. 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: "\22CF";} </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+22CF. 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 |
|---|---|
| 22CF [Hold down Alt] [Press x] | ⋏ (The 22CF turns into ⋏. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u22CF" document.write("My symbol: " + str) | My symbol: ⋏ |
