Distributive Property

 

(distributive law), the property of multiplication expressed by the identities c(a + b) = ca + cb and (a + b)c = ac + be. In a more general sense, the distributive property of the operator F(x) with respect to some operation x * y is referred to as a property expressed by the equality F(x *y) = F(x) * F(y). For example, the equality (ab)n = anbn shows that the operator of involution is distributive with respect to the operation of multiplication but not with respect to the operation of addition, since, generally speaking, (a + b)nan + bn.

In particular, different tasks were chosen in order to present particular concepts in different ways, such as those tasks about the distributive property (a critically important understanding that numbers can be partitioned to make operating with them easier, for example 34 x 7 can be considered as [30 x 7] + [4 x 7]) and inverse relationship (another important understanding that sometimes it is easier and more efficient to use division even though the problem appears to be a multiplication one, for example, 24 x ?
They appropriately applied the distributive property of multiplication to calculate 48 by 11 ("48 by 10 equals 480, plus another 48 equals 528"), and then added 48 more to work out the total number of Smarties if 12 were the average (576), and another 48 to work out the total number if 13 were the average (624).
