The Mathematical Symbol "Squared Times (⊠)"

The "Squared Times" (⊠)

The ⊠ symbol, commonly referred to as the "Squared Times" or "Times with Box", combines the multiplication cross with a square shape around it. While not as commonly encountered as some other mathematical symbols, it has its specific applications.

Common Uses of ⊠

The use of ⊠ can be domain-specific, and its meaning can change depending on the context. Here are some potential uses and scenarios:

  • Mathematics: In specific mathematical contexts or notations, the squared times symbol might be used to represent a unique operation or function distinct from regular multiplication.
  • Computational Operations: Sometimes, specialized symbols like ⊠ can be used in computational algorithms or software to denote specific operations or processes that shouldn't be confused with standard operations.


Here are some hypothetical examples of how the ⊠ might be used:

  1. In a mathematical paper, a new operation might be introduced: "For two elements, \(a\) and \(b\), the operation \(a ⊠ b\) represents ..."
  2. In software documentation, the symbol could be introduced to denote a unique operation: "When you see ⊠ between two variables, it indicates the custom multiplication function as defined in Module X."

Typing ⊠

In HTML and web-based content, the ⊠ entity can be used to display the squared times symbol. For most general document editing software or word processors, this symbol might not be readily available and may require special character maps or tools to be inserted.


The ⊠ symbol is a specialized mathematical symbol with potential applications in various mathematical or computational contexts. As with many unique symbols, understanding its exact meaning requires contextual information, and users should ensure clarity when introducing or using it in their work.

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 8864. 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: &#8864;</b>My symbol: ⊠

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

HTML TextOutput
<b>My symbol: &timesb;</b>My symbol: ⊠

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

CSS and HTML TextOutput
span:after {
content: "\22A0";}
<span>My symbol:</span>
My symbol: ⊠

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

HTML TextOutput
<b>My symbol: &#x22A0;</b>My symbol: ⊠
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22A0 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+22A0. 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 22A0 turns into ⊠. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22A0. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22A0"
document.write("My symbol: " + str)
My symbol: ⊠
