Less Than or Equal to Sign – Quick Answer

The less than or equal to sign (≤) shows that one value is either smaller than another or exactly equal to it.

Examples:

• x≤10x ≤ 10x≤10 → x can be 10, 9, 8, …
  
• In a spreadsheet: =IF(A1<=B1, “Yes”, “No”)
  
• In coding: if (score <= 50) → checks if score is 50 or less
  

It is a shortcut to express “less than or equal to” in one symbol.

The Origin of Less Than or Equal to Sign

The symbol ≤ combines the less than sign (<) with an underline (=) to represent equality as well.

• First used in the 16th–17th centuries by mathematicians in Europe.
  
• Developed for efficiency in algebra, calculus, and inequalities.
  
• Spelling differences in the phrase (less than or equal to vs. less-than-or-equal-to) exist due to grammar styles in English.

British English vs American English Spelling

Both British and American English use the same symbol ≤, but text styles vary:

Style	Example Phrase	Notes
American English	less than or equal to	Common in US textbooks and coding
British English	less-than-or-equal-to	Hyphenated in UK writing
Formal Math Writing	≤	Universal symbol

In short, the symbol ≤ stays the same; only the wording differs.

Which Spelling Should You Use?

• US audiences: Use “less than or equal to”
  
• UK/Commonwealth: Use “less-than-or-equal-to”
