The "Squared Plus" (⊞)

The ⊞ symbol is a mathematical symbol that represents the operation of addition, but with a squared context. It isn't as universally recognized as the standard plus (+) sign, but it has its significance in specific mathematical contexts.

## Basics of ⊞

The symbol ⊞ typically denotes a specific kind of addition operation that is squared in nature. This can be seen as a special operation or representation in certain mathematical domains.

## Understanding the Symbolism

The "plus" in the ⊞ symbol represents the addition operation, while the "square" aspect can be seen as encapsulating or emphasizing the additive operation in a specific manner. The exact interpretation can vary based on the context in which it's used.

## Applications

The exact applications of ⊞ can vary, and it's more commonly seen in specialized areas of mathematics or physics where specific notations are required to show certain operations or relationships. It might be used in algebraic contexts or when dealing with certain kinds of matrices or transformations.

## Typing ⊞

In HTML and web content, using the ⊞ entity will render the "Squared Plus" symbol. If working in specialized mathematical software or notation systems, other methods might be used to input this symbol.

## Related Symbols

Related symbols in the family might include ⊠ (Squared Times) or ⊟ (Dot Minus). These symbols, like ⊞, offer specialized notation for specific mathematical contexts or operations.

## Conclusion

The ⊞ symbol showcases the detailed and varied nature of mathematical notation. While it might be less common than other symbols, its usage can provide clarity and specificity in the mathematical statements or equations where it appears.

## Codes for the ⊞ Symbol

 The Symbol ⊞ Alt Code Alt 8862 HTML Code ⊞ HTML Entity ⊞ CSS Code \229E Hex Code ⊞ Unicode U+229E

## 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 8862. 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: &#8862;</b>My symbol: ⊞

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

HTML TextOutput
<b>My symbol: &plusb;</b>My symbol: ⊞

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

CSS and HTML TextOutput
<style>
span:after {
content: "\229E";}
</style>
<span>My symbol:</span>
My symbol: ⊞

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

HTML TextOutput
<b>My symbol: &#x229E;</b>My symbol: ⊞
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x229E 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+229E. 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
229E
[Hold down Alt]
[Press x]

(The 229E turns into ⊞. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u229E. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u229E"
document.write("My symbol: " + str)
My symbol: ⊞

## More about Mathematical Symbols

Mathematics is a universal language that is used to describe and understand the intricacies of the universe. At the heart of this language are symbols, concise representations that convey specific meanings and ideas.

Just as letters come together to form words in spoken languages, mathematical symbols combine to form expressions and equations, encapsulating intricate ideas in a compact form. The history of these symbols is as varied as their meanings; some have been in use for centuries while others have been introduced more recently to describe new discoveries and concepts. Whether you are a student, educator, researcher, or simply curious, this list of mathematical symbols will serve as a guide, shedding light on their meanings, origins, and applications.

From the simple plus and minus signs to the more esoteric and complex, each symbol has its unique story and significance.
