I'd definitely recommend the abacus for not only people that excel in math, but especially for people/kids who have a hard time with math. Using the abacus teaches a new way of thinking about math. I only wish I had known about the abacus when I first met my wife and her kids were younger. I think it would have made a huge difference to my stepson who isn't a math natural as he went through school.
