The distributive law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

The dividend is the amount we are dividing.

Explain how the distributive law applies to division expressions with a common divisor

Maths

In this unit pupils will explain how addition and subtraction can help to solve multiplication and division problems efficiently. They will learn how the distributive law applies to division expressions with a common divisor and using the distributive law to solve equations. In the future unit pupils will use priority of operations with positive and integers and decimals.

In the prior unit pupils explained the use of the commutative and associative laws when multiplying 3 or more numbers. In this unit pupils will explain how addition and subtraction can help solve multiplication and division problems. They will learn how the distributive law applies to division expressions with a common divisor and use their knowledge of the distributive law to solve equations.
