This document explains composite numbers, defined as numbers with more than two factors, and categorizes numbers into types such as even, odd, factors, multiples, squares, square roots, primes, and composites. It provides examples of composite numbers, their factors, and exercises to identify composite numbers from a given list. Additionally, it offers a recap of the lesson's content and a suggestion for further learning on square roots.

2. TYPES OF NUMBERS
 Numbers can be separated into different categories
according to some specific characteristics.These
categories include:
Even Numbers
Odd Numbers
Factors
Multiples
Square
Square Root

We will explain each of these categories in more detail.

3. TYPES OF NUMBERS
COMPOSITE NUMBERS
 A composite number is a number that has MORETHAN
TWO factors.
E.g. of Composite Numbers: 4, 6, 8, 9, 10
Composite Factors
4 1, 2, 4
6 1, 2, 3, 6
8 1, 2, 4, 8
9 1, 3, 9
10 1, 2, 5, 10

4. TYPES OF NUMBERS
COMPOSITE NUMBERS
Here are the different ways of deriving the
composites from their factors:
Composite Factors
4 1 x 4 or 2 x 2
6 1 x 6 or 2 x 3
8 1 x 8 or 2 x 4
9 1 x 9 or 3 x 3
10 1 x 10 or 2 x 5
