In this worksheet, we use the distributive law for subtraction.

 

Example

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

 

63×12 - 63×2 =
A
-
B
=
C

 

63×(12-2) =
D

 

Answer

A = 756
B = 126
C = 630
D = 630

This means that   63 x 12 - 63 x 2   is the same as   63 x (12 - 2)

This is the DISTRIBUTIVE LAW and makes it easier to work out the answer as 12 - 2 = 10

so we easily get     63 x 10 = 630
