Properties of Operations in Mathematics

The video tutorial reviews the five properties of real numbers: commutative and associative properties of addition and multiplication, and the distributive property. Each property is explained with examples, demonstrating how the order or grouping of numbers affects the result. The tutorial concludes with a recap of the properties and their applications.

What does the commutative property of addition state?

• A + B = B + A

• A * B = B * A

• A + B + C = A + (B + C)

• A * (B + C) = A * B + A * C

Which of the following is an example of the associative property of addition?

• 2 * (3 + 4) = 2 * 3 + 2 * 4

• 2 + 3 = 3 + 2

• 2 * 3 = 3 * 2

• (2 + 3) + 4 = 2 + (3 + 4)

What does the associative property of multiplication state?

• (A * B) * C = A * (B * C)

• A * B = B * A

• A + B = B + A

• A * (B + C) = A * B + A * C

Which equation is an example of the associative property of multiplication?

• 2 * (3 + 4) = 2 * 3 + 2 * 4

• 2 * 3 = 3 * 2

• 2 + 3 = 3 + 2

• (2 * 3) * 4 = 2 * (3 * 4)

What is the distributive property?

• A * B = B * A

• (A * B) * C = A * (B * C)

• A * (B + C) = A * B + A * C

• A + B = B + A

Which of the following demonstrates the distributive property?

• 2 * 3 = 3 * 2

• 2 * (3 + 4) = 2 * 3 + 2 * 4

• 2 + 3 = 3 + 2

• (2 * 3) * 4 = 2 * (3 * 4)
