Oscar Verhaeghe of Uccle, Belgium, could multiply four-digit numbers by two-digit numbers in 15 seconds without pencil and paper. Verhaeghe could give square roots, cube enormous numbers, and square large sums in less than half a minute. Once, under test conditions, he calculated the square of 888,888,888,888,888 in 40 seconds (the answer is 790,123,426, 790,121,876,543,209,876,544). Except for his mathematical ability, Verhaeghe had the mental capacity of a child.
