Mixed Operations

Some maths problems use more than one operation. You need to decide which operation to use: add, subtract, multiply, or divide.

Your goals

  • You can solve problems with different operations.
  • You can use operation, inverse correctly.
  • You can explain why each operation matches the question.

Words to know

operation:
A mathematical action such as addition, subtraction, multiplication, or division.
inverse:
An operation that undoes another operation.

Examples

  • 1"Mum bought 3 packs of 4 eggs and used 5. How many left?" → 3 × 4 = 12, then 12 − 5 = 7.
  • 2"A class of 24 is split into 6 groups. How many in each?" → 24 ÷ 6 = 4.

Check these

  • Do not choose an operation from one keyword without reading the whole problem.
  • Keep every number, symbol, label, and unit in its correct place.
  • Show enough working to check how you reached your answer.

Helpful habits

  • Read the whole question before choosing what to do.
  • Show one clear step at a time and check each step.
  • If you are stuck, draw a model, try smaller numbers, or revisit the example.

Now try your own

Create your own mixed operations example, solve it, and explain how you checked it.
