It's been a long time since I did sums by counting on my fingers. What changed so I could do them in my head?

Neuroscientists have worked out that a bit of the brain called the hippocampus changes as you do more sums. As you get older you start to memorise simple sums and the hippocampus, which plays a big role in memory, changes to enable you to do maths in your head.

The study involved scanning the brains of children, teenagers and adults to see how they changed.

How quick are you at sums?

Our brains gradually change as we get older, enabling us to move from counting on our fingers to sums in our heads.
