Equals Sign

The Mathematical Symbol "Equals Sign (=)"

The = Symbol in Mathematics: Equals Sign

Amidst the plethora of mathematical symbolsthe = symbolcommonly known as the "Equals Sign"stands as one of the most fundamental and universally recognized. Its introduction revolutionized mathematical notationproviding a clear way to show equality.

Usage

The = symbol is employed to indicate that two quantities or expressions are identicalmeaning they represent the same value. Its use permeates almost every facet of mathematicsfrom basic arithmetic to advanced equations in higher mathematics.

Examples

• Example 1: In basic arithmetic:
  \( 2 + 3 = 5 \)
  This demonstrates that the sum of 2 and 3 is equal to 5.
• Example 2: In algebraic equations:
  \( x^2 + 2x + 1 = (x + 1)^2 \)
  Herethe polynomial on the left side of the equals sign is identical in value to the squared binomial on the right side.

In essencethe = symbol serves as a foundational building block in mathematical notationenabling mathematicians to communicate equivalencies with clarity and precision. Its pervasive use across mathematical disciplines attests to its critical importance and universal acceptance.

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 (copyingreplacingeditingpasting)otherwise it will render as random characters or the dreaded �.

(Method 2) Use the "Alt Code."

If you have a keyboard with a numeric padyou can use this method. Simply hold down the Alt key and type 61. When you lift the Alt keythe symbol appears. ("Num Lock" must be on.)

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

HTML Text	Output
<b>My symbol: &#61;</b>	My symbol: =

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

HTML Text	Output
<b>My symbol: &equals;</b>	My symbol: =

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

CSS and HTML Text	Output
<> span:after { content: "\003D";} </> <span>My symbol:</span>	My symbol: =

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

HTML Text	Output
<b>My symbol: &#x003D;</b>	My symbol: =

On the assumption that you already have your canvas and the context set upuse the Hex code in the format 0x003D to place the = symbol on your canvas. For example:

JavaScript Text
const x = "0x"+"E9" ctx.fillText(String.fromCodePoint(x)55);
Output
=

(Method 7) Use the Unicode (for variouse.g. Microsoft OfficeJavaScriptPerl).

The Unicode for = is U+003D. The important part is the hexadecimal number after the U+which is used in various formats. For examplein Microsoft Office applications (e.g. WordPowerPoint)do the following:

Type	Output
003D [Hold down Alt] [Press x]	= (The 003D turns into =. Note that you can omit any leading zeros.)

In JavaScriptthe syntax is \uXXXX. Soour example would be \u003D. (Note that the format is 4 hexadecimal characters.)

JavaScript Text	Output
let str = "\u003D" document.write("My symbol: " + str)	My symbol: =
