## The Mathematical Symbol "Contains with Vertical Bar At End of Horizontal Stroke (⋻)"

The ⋻ Symbol in Mathematics: Contains with Vertical Bar At End of Horizontal Stroke

Mathematics is rich with symbols, each offering a unique expression or relation. One of the more specialized symbols is the ⋻, which denotes "Contains with Vertical Bar At End of Horizontal Stroke". This article provides insights into this symbol's interpretation and examples of its use.

## Usage

The ⋻ symbol is a variant of the 'contains' or 'element of' symbol found in set theory. While the traditional symbol indicates membership of an element in a set, this variant adds a level of specificity or nuance. The exact interpretation might vary depending on the context or the particular mathematical framework in question.

## Examples

**Example 1:**Given a specialized set context:

\( a ⋻ S \)

This might mean that \( a \) has a special kind of membership in the set \( S \), perhaps satisfying certain additional conditions or criteria.**Example 2:**In a refined logical or set-theoretic framework:

\( x ⋻ T \)

Here, \( x \) might be related to the set \( T \) under a unique membership rule, distinguished from the standard element-of relation.

In summary, while the ⋻ symbol is less commonplace than many mathematical notations, its presence underscores the depth and nuance of mathematical relations. Recognizing its significance helps in navigating advanced mathematical contexts with precision and clarity.

## Codes for the ⋻ Symbol

The Symbol | ⋻ | |

Alt Code | Alt 8955 | |

HTML Code | ⋻ | |

HTML Entity | ⋻ | |

CSS Code | \22FB | |

Hex Code | ⋻ | |

Unicode | U+22FB |

## 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 8955. 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: "\22FB";} </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: ⋻ |

**0x22FB**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+22FB**. 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 |
---|---|

22FB [Hold down Alt] [Press x] | ⋻ (The 22FB turns into ⋻. Note that you can omit any leading zeros.) |

JavaScript Text | Output |
---|---|

let str = "\u22FB" 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.
