Chapter: Number And Quantity
1. Understanding Whole Numbers
Whole numbers are the set of numbers beginning at zero and increasing in increments of one without fractions or decimals: 0, 1, 2, 3, and so on. They represent complete units and are used for counting discrete items such as people, objects, and events. They do not include negative numbers, fractions, or decimal values.
The set of whole numbers is infinite, meaning there is no largest whole number; counting can continue without end. Whole numbers are a subset of integers, and understanding their properties is essential for recognizing patterns, solving equations, and working with factors and multiples.
2. Factors
A factor is a whole number that divides another whole number exactly, leaving no remainder. Factors describe how a number can be broken down into smaller equal parts.
