## The Mathematical Symbol "Superset Of (⊃)"

The "Superset Of" Symbol (⊃)

The ⊃ symbol represents the mathematical concept of a "superset." In set theory, if every element of set A is also an element of set B, then B is a superset of A.

## Visual Representation

The ⊃ symbol visually appears similar to the ">" symbol, but is intended to be horizontal, akin to the "less than" (<) symbol tilted 90 degrees clockwise. However, instead of implying a relationship of greater value, in set theory, it indicates that one set contains all the elements of another set (and possibly more).

## Usage

The ⊃ symbol is used to depict relationships between sets. For instance, if A = {1, 2, 3} and B = {1, 2, 3, 4, 5}, then A is a subset of B, and B is a superset of A, which can be represented as:

A ⊂ B

B ⊃ A

## Typing ⊃

To represent the "Superset Of" symbol in documents or platforms that recognize HTML entities, you can use the ⊃ entity. However, the actual visual representation might vary slightly depending on the font and platform being used. For non-HTML contexts, other methods or dedicated libraries might be required to represent the symbol accurately.

## Related Symbols

Set theory offers a plethora of symbols to define relationships between sets. Some related symbols include:

• ⊂ (Subset Of)
• ⊆ (Subset of or Equal To)
• ⊇ (Superset of or Equal To)
• ⊄ (Not a Subset Of)
• ⊅ (Not a Superset Of)

## Conclusion

The ⊃ symbol is integral to set theory, representing the concept of one set containing all the elements of another. Proper understanding of this and related symbols is crucial for accurate representation and comprehension of relationships among sets. ## Are You Good at Mathematical Symbols?

## Codes for the ⊃ Symbol

 The Symbol ⊃ Alt Code Alt 8835 HTML Code ⊃ HTML Entity ⊃ CSS Code \2283 Hex Code ⊃ Unicode U+2283

## 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 8835. 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: &#8835;</b>My symbol: ⊃

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

HTML TextOutput
<b>My symbol: &sup;</b>My symbol: ⊃

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

CSS and HTML TextOutput
<style>
span:after {
content: "\2283";}
</style>
<span>My symbol:</span>
My symbol: ⊃

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

HTML TextOutput
<b>My symbol: &#x2283;</b>My symbol: ⊃
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2283 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+2283. 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:
TypeOutput
2283
[Hold down Alt]
[Press x]

(The 2283 turns into ⊃. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u2283. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u2283"
document.write("My symbol: " + str)
My symbol: ⊃
