Definition

What is it?

A number greater than a specific quantity means any number that has a larger value than that given quantity. When you compare two numbers, the one with the higher value is considered 'greater'.

Simple Example

Quick Example

Imagine you scored 85 marks in your Science exam. If your friend scored 90 marks, then 90 is a number greater than 85. It means your friend got more marks than you did.

Worked Example

Step-by-Step

Let's find a number greater than 15.
1. We need a number that has a value more than 15.
---
2. Start counting upwards from 15. The first number you reach after 15 is 16.
---
3. Compare 16 and 15. Is 16 bigger than 15? Yes, it is.
---
4. So, 16 is a number greater than 15. Other examples would be 17, 18, 100, etc.

Answer: 16 (or any number larger than 15)

Why It Matters

Understanding 'greater than' is fundamental to all mathematics, from basic counting to advanced algebra. It helps us compare values, order things, and make decisions. Engineers use it to compare strengths, economists use it to compare prices, and even doctors use it to compare health measurements.

Common Mistakes

MISTAKE: Confusing 'greater than' with 'less than' or 'equal to'. Forgetting which symbol to use. | CORRECTION: Remember 'greater than' means bigger. The open mouth of the '>' symbol always faces the bigger number. Think of it as a hungry crocodile wanting to eat the larger number.

MISTAKE: Forgetting that there are infinite numbers greater than any given number. Thinking there's only one answer. | CORRECTION: While 16 is the immediate next whole number greater than 15, any number like 17, 20, 100, or even 15.5 is also greater than 15.

MISTAKE: Not understanding how 'greater than' applies to negative numbers (e.g., thinking -5 is greater than -2). | CORRECTION: On a number line, numbers to the right are always greater. So, -2 is greater than -5 because -2 is to the right of -5.
