MultiplicationIt’s Associative!

One of the multiplication properties is associative, which meansyou can group the factors in a multiplication equation andstill get the same product.

A × (B x C) = (A x B) x C

MultiplicationIt’s Associative!

One of the multiplication properties is associative, which meansyou can group the factors in a multiplication equation andstill get the same product.

A × (B x C) = (A x B) x C

Find the missing number according to the associative property.

Find the product of these numbers.

When you group the factors di�erently, do the two equations have the same product?

4 x (3 x 2) = (4 x 3) x

7 x (2 x 1) =

10 x (3 x 4) = 10 x (3 x 4) =

6 x (2 x 5) = (6 x 2) x

2 x (7 x 1) =

(10 x 3) x 4 = x 4 =
