Combining Like Terms and the Distributive Property

Mrs. Bailey explains how to simplify algebraic expressions using the distributive property and combining like terms. She provides step-by-step examples, highlighting the importance of distributing before combining terms. The video includes practical tips, such as using an area model and tic-tac-toe board for handling negatives, and encourages students to practice independently.

What are the two main steps discussed for simplifying expressions?

• Distribution and combining like terms

• Addition and subtraction

• Distribution and subtraction

• Combining like terms and multiplication

Why is it important to note the sign in front of a number when using the distributive property?

• It influences the multiplication of terms inside the parentheses

• It has no effect on the distribution

• It determines the direction to move on the number line

• It changes the terms inside the parentheses
