Understanding the Distributive Property

This video tutorial by Stan Lyall covers the distributive property in algebra. It begins with an introduction to the concept, followed by examples using real numbers to demonstrate how the property works. The tutorial also covers undistributing numbers and using mental math for easier calculations. Practice problems are provided to reinforce learning, and the video concludes with a section on using variables and solving word problems. Viewers are encouraged to practice further using worksheets available online.

What is an example of distribution in everyday life?

What is the result of undistributing 10 + 5?

• 5 * (3 + 1)

• 5 * (1 + 2)

• 5 * (2 + 3)

• 5 * (2 + 1)

How can the distributive property help with mental math?

• By allowing division of numbers

• By making calculations more complex

• By simplifying multiplication into smaller parts

• By eliminating the need for addition

What is the result of 50 * 12 using the distributive property?

• 500 + 200

• 600 + 200

• 500 + 100

• A mathematical operation

• A type of equation

• A fixed number

How can you express your mother's age if she is three times older than your sister, who is X years older than you?

• 3 * (11 + X)

• 3 + (11 * X)

• 3 * (X - 11)

• 3 + (X + 11)
