The greater than (>) and less than (<) symbols are among the most common mathematical operators. They are used to compare two values, showing which number, amount, or expression is larger or smaller. Beyond mathematics, these symbols also carry meaning in programming, logic, and everyday digital use.
Quick Picks: Key Facts About Greater Than and Less Than Symbols
- Less Than Symbol (<): Means the number on the left is smaller than the number on the right. Example: 3 < 5.
- Greater Than Symbol (>): Means the number on the left is larger than the number on the right. Example: 7 > 2.
- Origin: Introduced by mathematician Thomas Harriot in the 17th century.
Mathematical Usage
- < (Less Than): Compares two values, showing the first is smaller. Example: 4 < 10.
- > (Greater Than): Compares two values, showing the first is larger. Example: 15 > 9.
- ≤ (Less Than or Equal To): Indicates the left side is smaller or equal. Example: 5 ≤ 5.
- ≥ (Greater Than or Equal To): Indicates the left side is larger or equal. Example: 8 ≥ 6.
How to Remember the Symbols
- The open side of the symbol always faces the larger number.
- Think of the symbol as a hungry alligator: the wide-open mouth (< or >) “eats” the bigger number.
- Example: For 2 < 9, the “alligator” faces the 9, the larger value.
Other Uses of Greater Than and Less Than Symbols
- Programming: Used in conditional statements (e.g., if x > y).
- HTML: Angle brackets (< >) are used to define tags in web coding.
- Logic: Used in inequalities to compare variables or values.
- Digital Culture: Sometimes used to create emoticons or shorthand (e.g., <3 for a heart).
Comparison Table: Greater Than vs. Less Than
| Symbol | Name | Meaning | Example |
|---|---|---|---|
| < | Less Than | Left side is smaller | 3 < 8 |
| > | Greater Than | Left side is larger | 10 > 4 |
| ≤ | Less Than or Equal To | Left side is smaller or equal | 5 ≤ 5 |
| ≥ | Greater Than or Equal To | Left side is larger or equal | 7 ≥ 3 |
FAQ: Greater Than and Less Than Symbols
What does the less than symbol mean?
It shows that the left-hand value is smaller than the right-hand value. Example: 2 < 6.
What does the greater than symbol mean?
It shows that the left-hand value is larger than the right-hand value. Example: 9 > 1.
What is the difference between < and ≤?
< means strictly less than, while ≤ means less than or equal to.
Who invented the symbols?
Mathematician Thomas Harriot first introduced the symbols in 1631.
Can these symbols be used outside of math?
Yes. They are used in coding, logic, and even internet shorthand (like <3 for a heart).
Conclusion
The greater than (>) and less than (<) symbols are simple yet powerful tools for comparison in math, coding, and daily life. Remembering that the open side of the symbol always faces the larger value makes them easy to use. Whether in equations, programming, or digital culture, these symbols continue to serve as essential tools for communication and expression.
