Introduction to Negative Numbers

This page introduces the fundamental concepts of positive and negative numbers through visual representation on a number line. The content explains the basic definitions and characteristics of these numbers.

Definition: A positive number is any number greater than zero.

Example: Positive numbers include 2, 5, 3, 7, and other values greater than zero.

Definition: A negative number is any number less than zero and moves in the opposite direction of positive numbers.

Example: Negative numbers include -1, -5, -7, -3, -4, and other values less than zero.

Highlight: The number line clearly shows how positive numbers progress to the right while negative numbers extend to the left.
