They believe in future the technique may help people with dyscalculia, or "number blindness" – the mathematical equivalent of dyslexia.More info at BBC News.
But it is important to get the wiring right. If the electricity flows in the wrong direction it has the opposite effect, creating a person with a poor head for figures.
Volunteers who received the right-left stimulus reached double the level of performance in the tests compared to the non-stimulated group after just a few sessions, the scientists reported in the journal Current Biology.
In contrast, those stimulated with a left-right current saw their performance drop to about the same level as six-year-old children.
Students who received a fake "placebo" stimulus had results that fell half way between those of the other two groups.

Researchers at Oxford University discovered that passing a low electric current through a specific region of the brain can double your ability to do mathematics for up to six months:
