Prime Factorization and Basic Operations

This video tutorial covers essential math concepts including multiplication and division techniques, inverse operations, and the order of operations (BODMAS). It explains how to multiply and divide by powers of ten, identify prime and composite numbers, and perform prime factorization. The tutorial also explores finding the lowest common multiple and highest common factor, understanding square and cube numbers, and applying the commutative and distributive laws.

What is the first step in multiplying a four-digit number by a two-digit number?

• Divide the numbers first

• Arrange the columns and put titles on top

• Add all the numbers together
