## The Mathematical Symbol "Neither Less-Than nor Equal To (≰)"

Understanding the "Neither Less-Than nor Equal To" Symbol (≰)

Mathematical notation, with its intricate web of symbols, elegantly communicates complex ideas in a concise manner. One such symbol is ≰, representing "Neither Less-Than nor Equal To".

## Understanding ≰

The ≰ symbol articulates a specific comparative relationship between two values or entities. When invoked, it asserts that one value is neither less than nor equal to the other. This differentiates the values distinctly, emphasizing that the first is strictly greater than the second.

Example 1: Numerical Relations

Given two numbers, a and b, stating $$a ≰ b$$ implies that a is not less than and also not equal to b. Hence, a is strictly greater than b.

Example 2: Theoretical Applications

Assuming we're analyzing sequences in mathematics where the terms $$S_n$$ and $$T_n$$ represent the nth terms of two sequences. If it's observed that $$S_n ≰ T_n$$ for all values of n, it's clear that $$S_n$$ always exceeds $$T_n$$ for every term in the sequence.

## Domains Employing ≰

The symbol ≰ can be encountered across various mathematical and related areas:

• Algebra: In inequalities and algebraic proofs.
• Calculus: Especially in the study of limits and functions.
• Statistics: When contrasting data points or metrics.

The symbol ensures precision when delineating relationships, ensuring there's no ambiguity in comparative discussions.

In summary, the ≰ symbol, signifying "Neither Less-Than nor Equal To", is paramount for capturing specific relationships with clarity. It stands testament to the depth and richness of mathematical notation, ensuring intricate ideas can be communicated seamlessly. ## Are You Good at Mathematical Symbols?

## Codes for the ≰ Symbol

 The Symbol ≰ Alt Code Alt 8816 HTML Code ≰ HTML Entity ≰ CSS Code \2270 Hex Code ≰ Unicode U+2270

## 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 8816. 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: &#8816;</b>My symbol: ≰

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

HTML TextOutput
<b>My symbol: &nle;</b>My symbol: ≰

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

CSS and HTML TextOutput
<style>
span:after {
content: "\2270";}
</style>
<span>My symbol:</span>
My symbol: ≰

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

HTML TextOutput
<b>My symbol: &#x2270;</b>My symbol: ≰
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2270 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+2270. 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
2270
[Hold down Alt]
[Press x]

(The 2270 turns into ≰. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u2270. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u2270"
document.write("My symbol: " + str)
My symbol: ≰
