## The Mathematical Symbol "Greater-Than or Less-Than (≷)"

The ≷ Symbol in Mathematics: Greater-Than or Less-Than

The ≷ symbol is a lesser-known mathematical notation that carries a nuanced meaning. Often mistaken for the more common inequality symbols, ≷ serves to express a more specific relational concept. This article seeks to clarify its role and offers examples for enhanced comprehension.

## Usage

At a glance, the ≷ symbol can appear to be a conflation of the "greater than" (>) and "less than" (<) symbols. In specific mathematical contexts, it may denote that two quantities are incomparable within a given order or that their relational order is complex or multi-dimensional.

## Examples

**Example 1:**Incomparable Elements:

Let's consider a partial order on a set where not all elements can be straightforwardly compared. In such a scenario, if \( a \) and \( b \) are two elements that don't adhere to a simple order relation, we could express their incomparability as \( a ≷ b \).**Example 2:**Multi-Dimensional Order:

Suppose we are comparing two vectors in a plane, Vector A and Vector B. If the vectors don't have a straightforward dominant order in both dimensions, the relationship might be denoted as Vector A ≷ Vector B, indicating the multi-faceted nature of their comparison.

In closing, the ≷ symbol is a specialized notation that comes to the fore in certain mathematical settings, particularly where standard order relations aren't adequate. Its use emphasizes the need to comprehend the specific context or mathematical structure in which it appears.

## Codes for the ≷ Symbol

The Symbol | ≷ | |

Alt Code | Alt 8823 | |

HTML Code | ≷ | |

HTML Entity | ≷ | |

CSS Code | \2277 | |

Hex Code | ≷ | |

Unicode | U+2277 |

## 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 8823. 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: "\2277";} </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: ≷ |

**0x2277**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+2277**. 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 |
---|---|

2277 [Hold down Alt] [Press x] | ≷ (The 2277 turns into ≷. Note that you can omit any leading zeros.) |

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

let str = "\u2277" document.write("My symbol: " + str) | My symbol: ≷ |
