The commutative property of multiplication states that the order of the numbers in an equation:

• Should go from least to greatest
• Doesn't change the product
• Should go from greatest to least
• Is always important

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

Rewrite (9 x 6) x 5 using the associative property.

• 270
• 9 x 30
• 9 x (6 x 5)
• 5 x 9 + 5 x 6

9+0=9
