Dyscalculia is a bit like dyslexia - that's when people get letters and words mixed up and find it difficult to read. But dyscalculia affects numbers instead of words.
Experts think it could affect as many as one person in every class.
If you have dyscalculia you might find it hard to work out how numbers relate to each other.
For example you might find it really difficult to say which of these numbers is bigger: five or seven.
Dyscalculia can also mean finding it difficult to:
- Hear numbers
- Understand numbers
- Write numbers.
Although it affects everyone differently, it means you might find it hard to:
- Tell the time
- Work out prices in shops
- Work out pocket money
- Work out exact temperatures
- Work out exactly how fast something is going
What should I do?
Being bad at maths doesn't necessarily mean you've got dyscalculia.
But if you are having really big problems, you should speak to your teacher or your parents about it. They can arrange for you to take special tests.
If you have got dyscalculia you can learn ways to cope in your day-to-day dealings with numbers, and of course that will help you loads in maths lessons, too.
