The Mathematical Symbol "Greater-Than with Dot (⋗)"
The ⋗ Symbol in Mathematics: Greater-Than with Dot
Among the myriad of mathematical symbols, the ⋗ stands out as the "Greater-Than with Dot". This article aims to shed light on its meaning and offer examples for better comprehension.
Usage
The ⋗ symbol is a less common variation of the familiar "greater than" symbol. While its specific interpretation can vary depending on the context, it's often employed in specialized areas of mathematics, such as number theory or certain algebraic structures, to denote a specific type of ordering or relation.
Examples
- Example 1: Special Order Relations:
Suppose we have an order relation on a set that is slightly different from the typical less-than or greater-than relations. In some contexts, the ⋗ might be used to express this special relation, for instance, when comparing the order of certain elements: \( a ⋗ b \). - Example 2: Notational Distinctions:
In some mathematical discussions, especially those involving multiple order relations, the ⋗ can be employed to distinguish between them. For instance, while \( a > b \) might indicate a typical ordering, \( a ⋗ b \) might denote a special type of relation within the same context.
In summary, the ⋗ symbol serves as a specialized notation to express distinct or nuanced "greater than" relations. Its usage is context-dependent, making it vital to understand the specific mathematical framework where it's being employed.

| 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: "\22D7";} </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+22D7. 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 |
|---|---|
| 22D7 [Hold down Alt] [Press x] | ⋗ (The 22D7 turns into ⋗. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u22D7" document.write("My symbol: " + str) | My symbol: ⋗ |
