Struggle with maths? Scientists say zapping the BRAIN can improve your skills

Zapping the brain could help people who struggle with maths get better at arithmetic. Researchers gave 102 people a set of tricky arithmetic problems, which each involved multiplying a double-digit number by a single-digit number, like 16 x 3 48. Half of the people in the study had their brain zapped with a mild electric current to stimulate their brain cells. People given the brain stimulation, and also tested under more difficult learning conditions, answered the questions in about half the time, compared to people whose brains were not zapped, researchers claim. They reportedly got the answers 52 per cent quicker.
