Fascinating Fact:

If you swap the order in an addition, the answer doesn’t change, it’s like 5 + 7 or 7 + 5, both give you 12.

In KS2 Maths, Year 3 pupils practise using addition and subtraction in written and mental forms. These skills support problem solving in real life and prepare learners for advanced number work.

Key Terms

Addition: Combining two or more numbers to find the total.
Subtraction: Taking one number away from another to find the difference.
Sum: The result you get when numbers are added together.

Frequently Asked Questions (Click to see answers)

What is the commutative property in addition?

The commutative property means you can swap the order of numbers in addition and still get the same answer, for example 3 + 8 is the same as 8 + 3.

Why is subtraction not commutative?

Subtraction is not commutative because changing the order of the numbers changes the answer. For example, 9 - 5 is 4 but 5 - 9 is -4.

How can I check my subtraction answers?

You can check subtraction by using addition. For example, if 15 - 7 = 8, then adding 8 + 7 should bring you back to 15.
