Multiplying and Understanding Factors

This video tutorial teaches how to multiply multiples of ten by breaking them into two factors. It explains the concept of place value and the commutative property of multiplication. The lesson introduces a three-step process for multiplying by ten, demonstrated through example problems. The tutorial concludes with a recap of the key concepts and a final example problem.

What is a multiple of ten?

• A number that is a factor of ten
