Have you ever thought about how mathematicians are able to explain complex ideas through a few strokes of a pen? Mathematical symbols are the language of mathematics, simplifying things and making problem-solving effective. From comparing quantities to explaining relationships, symbols like the greater than symbol (>) and less than sign (<) are essential tools for students. For parents and 1-12 students, understanding these symbols is the first step towards mastering math concepts.
Unlock Your Child’s Math Potential
Let's have a glance at important mathematical symbols, their significance, and how they're used in real life.
Why are mathematical symbols so essential?
Math symbols are short forms for writing down concepts that would otherwise need lengthy sentences. They help:
- Simplify computation and comparison.
- Waste less time by simplifying problem-solving.
- Offer a common method of expressing mathematical concepts in all languages and cultures.
Key Math Symbols
Here's a list of some fundamental mathematical symbols:
|
Symbol |
Name |
Meaning |
Example |
|
+ |
Addition |
Combines two numbers or values |
3 + 2 = 5 |
|
- |
Subtraction |
Finds the difference between two numbers |
4 – 2 = 2 |
|
× or · |
Multiplication |
Repeated Addition |
4 × 3 = 12 |
|
÷ or / |
Division |
Splits a number into equal parts |
8 ÷ 2 = 4 |
|
> |
Greater Than Symbol |
Indicates one value is larger than another |
10 > 5 |
|
< |
Less Than Sign |
Indicates one value is smaller than another |
3 < 7 |
|
= |
Equal To |
Shows two values are the same |
6 = 6 |
|
≥ |
Greater Than or Equal To |
Indicates one value is larger than or equal to another |
x ≥ 5 |
|
≤ |
Less Than or Equal To |
Indicates one value is smaller than or equal to another |
y ≤ 10 |
Learning Greater Than and Less Than Symbols
Greater Than Symbol (>)
The symbol > is employed to compare two values where the first value is greater than the second.
Example: 10 > 5 means "10 is greater than 5."
Less Than Sign (<)
The less than symbol is used to compare two values where the first value is smaller than the second.
Example: 3 < 7 means "3 is less than 7."
How to Remember
Imagine the symbol as being the mouth of an alligator - the open part always faces the larger number because the alligator likes to digest the larger meal!
Real-World Applications of Mathematical Symbols
Math symbols aren't only found in textbooks - there are everywhere in everyday life!
- Banking: Greater than and less than signs assist in comparing interest rates or balances.
- Shopping: Discounts usually involve percentages (e.g., "20% off").
- Weather Forecasts: Symbols like "+" and "-" indicate temperature variations.
- Engineering: Symbolic equations are used to construct bridges and machinery.
Fun Fact: Did You Know?
The earliest recorded use of the greater than (>), less than (<) symbols was in 1631 when English mathematician Thomas Harriot created them!

FAQs
Q1: What does the symbol > mean?Ans: The > symbol means that one value is larger than another (i.e., 10 > 5).
Q2: What is the symbol less than?Ans: The less-than sign (<) is employed when a number is smaller than another (e.g., 3 < 7).
Q3: How do I easily memorise these symbols?Ans: Visualise the symbol as the mouth of an alligator - the open end is facing the bigger number because it is hungry to eat more!
Q4: Are mathematical symbols universal?Ans: Indeed! Mathematical symbols are recognised worldwide, thereby becoming a common language between cultures.
Q5: Why are mathematical symbols useful in everyday life?Ans: Symbols enable comparison, calculation, and expression in areas like banking, shopping, engineering, and meteorology.
