Brackets are symbols used in pairs to group things together.

The order of operations is a set of rules that tell you which operations have priority over others in an equation.

Combine division with addition and subtraction

Maths

Combine multiplication with addition and subtraction

Explain how the distributive law applies to multiplication expressions with a common factor

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

Use knowledge of the order of operations to solve equations

In this unit pupils will explore what happens when we combine addition and subtraction with multiplication and division, bringing up the need for the order of operations. 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 explore what happens when we combine addition and subtraction with multiplication and division, bringing up the need for the order of operations.

Order of operations

Which expression represents how to find the total number of coins in these wallets?

Match the equations to the correct solutions. 

Aisha says that 3 + 12 ÷ 3 = 7 Jun says that 3 + 12 ÷ 3 = 5  Who is correct?

Compare the two expressions using < > or =

Jun needs to solve 11 x (3 + 2)     Which operation will he need to complete first?

Complete the equation: 12 × 3 + 5 × 12 = {{ }}

Using the distributive law, which expression would have the same solution as this expression?    11 × 2 + 11 × 3

Look for the common factor in the expressions and match the expressions that are equal.

Use the distributive law to solve this problem. Marbles come in bags of 30     Jun has 3 bags of marbles and Sam has double this amount. How many marbles do they have altogether? {{ }} marbles.
