Intro to Algebra Quiz

Which is an example of the commutative property of multiplication?

• 4 x(1 _^x 2) = (4 x 1) x 2
• 2 x 2 = 4 x 1
• 2(3) = 2(4)
• 3 x 4 = 4 x 3

Which of these illustrates the associative property of multiplication?

• 4 x (5 x 6) = (4 x 5) x 6
• 6 (9 + 1) = (6 x 9) + (6 x 1)
• 4 x (56) = (45) x 6
• 5 + 0 = 0 + 5
