Understanding the Distributive Property

The video tutorial introduces the distributive property, a mathematical concept used to simplify multiplication problems by breaking down larger factors into smaller, more manageable parts. It provides a step-by-step example of multiplying 18 by 7 using this property, demonstrating how to split 18 into 10 and 8, multiply each by 7, and then add the results to get the final product. The tutorial emphasizes the cleverness and utility of the distributive property in solving complex multiplication problems.

What is the distributive property used for?

• To add two numbers

• To break up a large factor and multiply the parts

• To subtract two numbers

• To divide two numbers
