The Mathematical Symbol "Succeeds or Equal To (≽)"
The "Succeeds or Equal To" Symbol (≽)
The ≽ symbol signifies a relation between two elements where one succeeds the other or is equal to it. This is mostly used in the context of order relations in mathematics.
Visual Representation
The symbol itself might look like a "greater than" sign (`>`) accompanied by an underline or a curve under it, illustrating the "or equal to" portion of its meaning.
Common Uses
The "Succeeds or Equal To" relation has specific applications in mathematics, especially when discussing ordered sets or sequences:
- Ordering: In an ordered set or sequence, if element \( a \) is either greater than or equal to element \( b \), then it can be expressed as \( a ≽ b \).
- Examples:
- For the set of real numbers, if \( x = 5 \) and \( y = 3 \), then \( x ≽ y \).
- In a sequence, if the 5th term is 7 and the 4th term is 7, we can also say the 5th term ≽ the 4th term.
Representation in Other Contexts
In LaTeX, which is often used for typesetting complex math formulas, the "succeeds or equal to" symbol can often be represented with commands like `\succeq` when you're within math mode.
Conclusion
The ≽ symbol serves a vital role in representing certain order relations in mathematics. By indicating "greater than or equal to," it simplifies expressions and provides a concise way to describe the relationship between elements in ordered sets.

Codes for the ≽ Symbol
| The Symbol | ≽ | |
| Alt Code | Alt 8829 | |
| HTML Code | ≽ | |
| HTML Entity | ≽ | |
| CSS Code | \227D | |
| Hex Code | ≽ | |
| Unicode | U+227D |
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 8829. 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: "\227D";} </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+227D. 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 |
|---|---|
| 227D [Hold down Alt] [Press x] | ≽ (The 227D turns into ≽. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u227D" document.write("My symbol: " + str) | My symbol: ≽ |
