The Mathematical Symbol "Equal To or Precedes (⋞)"

The ⋞ Symbol in Mathematics: Equal To or Precedes

Mathematics boasts a rich tapestry of symbols, each encapsulating a unique concept. Among them, the ⋞ symbol, signifying "Equal To or Precedes", holds particular relevance in order theory. In this article, we'll outline its significance, enhanced by relevant examples.


The ⋞ symbol is primarily employed within the realm of order theory, a branch of mathematics that deals with binary relations on sets. Specifically, it denotes that one element is either equal to another or precedes it in a certain order.


  • Example 1: Within a set of numbers \( S = \{1, 2, 3, 4\} \), if we have two elements \( a = 2 \) and \( b = 2 \):
    \( a ⋞ b \)
    This indicates that \( a \) is either equal to or precedes \( b \) in the order of set \( S \). In this case, \( a \) is equal to \( b \).
  • Example 2: Using the same set \( S \), for \( c = 2 \) and \( d = 3 \):
    \( c ⋞ d \)
    Here, \( c \) precedes \( d \) in the order defined by set \( S \).

To conclude, the ⋞ symbol provides a succinct way to convey the relationship between two elements in an ordered set. By indicating that one element is either equivalent to or precedes another, it captures essential relations within order theory and related mathematical areas.

Codes for the ⋞ Symbol

CSS Code\22DE
Hex Code⋞

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 8926. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

(Method 3) Use the HTML Decimal Code (for webpages).

HTML TextOutput
<b>My symbol: &#8926;</b>My symbol: ⋞

(Method 4) Use the HTML Entity Code (for webpages).

HTML TextOutput
<b>My symbol: &cuepr;</b>My symbol: ⋞

(Method 5) Use the CSS Code (for webpages).

CSS and HTML TextOutput
span:after {
content: "\22DE";}
<span>My symbol:</span>
My symbol: ⋞

(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).

HTML TextOutput
<b>My symbol: &#x22DE;</b>My symbol: ⋞
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22DE to place the ⋞ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"E9"
ctx.fillText(String.fromCodePoint(x), 5, 5);

(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).

The Unicode for ⋞ is U+22DE. 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:
[Hold down Alt]
[Press x]

(The 22DE turns into ⋞. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22DE. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22DE"
document.write("My symbol: " + str)
My symbol: ⋞
