Associative Property of Multiplication

The video tutorial explains how to compare two mathematical expressions using the order of operations, known as PEMDAS. It demonstrates evaluating expressions step-by-step and highlights the associative property of multiplication, showing that the grouping of factors does not affect the product. The lesson concludes with an algebraic representation of the associative property.

What is the correct order of operations to evaluate an expression?

• Multiplication, Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication and Division, Addition and Subtraction

• Exponents, Parentheses, Addition, Subtraction

• Parentheses, Multiplication, Addition, Subtraction

In the first expression, what is the result of evaluating the expression inside the parentheses?

• 3 * 2 = 6

• 5 * 3 = 15

• 3 * 5 = 15

• 5 * 2 = 10

What is the final result of both expressions after applying the order of operations?

• 25

• 30

• 35

• 40

What does the associative property of multiplication demonstrate?

• The grouping of factors affects the product

• The order of factors affects the product

• The grouping of factors does not change the product

• The order of operations is not important

How can the associative property of multiplication be represented algebraically?

• (a * b) * c = a * (b * c)

• a + (b + c) = (a + b) + c

• (a + b) * c = a * (b + c)

• a * b + c = a * (b + c)
