Number Line Introduction

A number line is a straight line that helps us understand the concept of numbers and their positions. It's a powerful tool for learning about mathematics, especially in topics like addition, subtraction, multiplication, and division.

Key Concepts

Origin: The starting point of the number line is called the origin.
Positive Numbers: Numbers to the right of the origin are positive.
Negative Numbers: Numbers to the left of the origin are negative.
Interval: The distance between two numbers on the line.

How to Use

Locating Numbers: To find a number on the line, move the specified interval from the origin.
Operations: Adding or subtracting involves moving along the line. Multiplying and dividing can be visualized by scaling the distance.

Example

Here's a simple example:

To add 3 to 5, start at 5 and move 3 units to the right. You end up at 8.
