Electroencephalographic changes by solving mathematical problems were tested on 52 healthy young subjects. Slow negative potentials appeared in the frontal lobe (Fz) when the subject was asked to add numerals presented by a slide projector, multiply them and add them while hearing other addition problems through headphones. The mean amplitude of the potential was larger in multiplication and in addition while hearing other addition problems than in addition.
