Applying a tiny electrical current to the brain could make you better at learning maths, according to Oxford University scientists.
They found that targeting a part of the brain called the parietal lobe improved the ability of volunteers to solve numerical problems.
They hope the discovery could help people with dyscalculia, who may struggle with numbers.
Another expert said effects on other brain functions would need checking.
The findings are reported in the journal Current Biology.
Some studies have suggested that up to one in five people have trouble with maths, affecting not just their ability to complete problems but also to manage everyday activities such as telling the time and managing money.
