Classifying Different Types of Numbers

In this video, Mr. Lara explains how to classify numbers into different categories: natural, whole, integer, and rational numbers. Natural numbers are counting numbers starting from 1. Whole numbers include all natural numbers and zero. Integers extend whole numbers to include negative numbers.
