Year 4 maths worksheet: 100 more than or less than

Maths worksheet from mathsblog.co.uk in association with MathSphere.co.uk

Adding or subtracting 100 from a number is usually straightforward, but can prove tricky if the number crosses the thousand mark. Normally this would be done mentally, without resorting to written methods.

For example 100 less than 3 456 is 3 356: only the hundreds digit needs to change.

More tricky is 100 less than 3095, which is 2905, involving both the hundreds digit and the thousands digit to change. Getting this type of question correct shows a good understanding of place value.
