In this activity, we will use the distributive law for addition.

 

Example

Work out the values of A, B, C and D.

 

5 x 3 + 5 x 4 = A + B = C

 

5 x (3 + 4) = D

 

Answer

A = 15
B = 20
C = 35
D = 35

 

This means that    5 x 3 + 5 x 4   is the same as   5 x (3 + 4)

 

This is the distributive law.

 

Let's have a go at some questions to help you to understand how it works.
