Square Original of or Equal To

The Mathematical Symbol "Square Original of or Equal To (⊒)"

The "Square Original of or Equal To" (⊒)

The ⊒ symbol, while less commonly recognized than some other mathematical symbols, has its place in order theory, a branch of mathematics that deals with the idea of "ordering" or arranging elements based on some criteria or relation.

Basics of ⊒

The symbol ⊒ typically denotes that an element is either "square original of" or "equal to" another element. This is commonly seen in contexts where relationships between sets or other mathematical objects are being described.

Understanding the Symbolism

At a high level, the "square" aspect of the symbol can be seen as a representation of a specific kind of ordering or relation, while the "equal to" portion (=) is more universally recognized as denoting equivalence between two entities.

Applications

The exact applications of ⊒ can vary based on the mathematical context in which it's used. However, it's primarily seen in advanced mathematical topics or research where the relationships between sets or elements are being studied in depth.

Typing ⊒

In HTML and web-based content, the use of the ⊒ entity will render the "Square Original of or Equal To" symbol. For specialized mathematical notation or software, there may be other specific methods for inputting this symbol.

Related Symbols

Other symbols in the family might include ⊑ (Square Image of or Equal To) or ⊐ (Square Original of). Understanding the subtle distinctions between these symbols is crucial for correctly interpreting the mathematical statements in which they appear.

Conclusion

The ⊒ symbol is an example of the richness and specificity of mathematical notation. While it might not be as universally recognized as some symbols, it plays a crucial role in the contexts where it is employed, facilitating precise and nuanced expressions of mathematical relationships.

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 8850. 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: &#8850;</b>	My symbol: ⊒

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

HTML Text	Output
<b>My symbol: &sqsupe;</b>	My symbol: ⊒

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

CSS and HTML Text	Output
<style> span:after { content: "\2292";} </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: &#x2292;</b>	My symbol: ⊒

On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2292 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+2292. 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
2292 [Hold down Alt] [Press x]	⊒ (The 2292 turns into ⊒. Note that you can omit any leading zeros.)

In JavaScript, the syntax is \uXXXX. So, our example would be \u2292. (Note that the format is 4 hexadecimal characters.)

JavaScript Text	Output
let str = "\u2292" document.write("My symbol: " + str)	My symbol: ⊒
