'The Distributive Law in Addition (Numbers <100)' worksheet

Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Use Relationships Between Operations

Difficulty level:  

Worksheet Overview

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

 

Example

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

 

59×3 + 59×7 =
A
+
B
=
C

 

59×(3 + 7) =
D

 

Answer

A = 177
B = 413
C = 590
D = 590

This means that    59 x 3 + 59 x 7   is the same as   59 x (3 + 7)

This is the DISTRIBUTIVE LAW and makes it easier to work out the answer as 3 + 7 = 10

so we easily get     59 x 10 = 590
