What is Number Theory?
Number theory is like being a detective for numbers!
It's the study of whole numbers and their special properties, patterns, and relationships. Today we'll review prime numbers, factors and multiples, divisibility rules, and more!

2️⃣ Factors are numbers that divide exactly into another number
