Distributive Property: Great tool\n\nSay you were multiplying 543 and 199, for example:\n\n543(199) = 543(200 - 1) = 543(200) - 543 = 543(2)(100) - 543 = 108,600 - 543 = 108,057\n\n78(15) = 78(10 + 10/2) = 780 + 780/2 = 780 + 390 = 1170\n\nI mean doubling and halving is usually easier to do in your head.

maybe you could try practising. For maths, the phrase practice makes perfect is very true. hmm...short cuts in multiplication and division...maybe you could try learning the abaccus (a mathematical instrument used by the chinese => functions like a calculator, but manually powered, no batteries)...I only know how to add and subtract using it...

I think a calculator would be great for this one! It sounds perfect for a math wiz to try...Good luck! MayMay

Write it down and look at it every once in a while. The other thing I do to remember numbers is to associate it with something that I cannot forget. Analogies work greatly in memory!

Try http://www.edhelper.com/number_puzzle.htm.  I don't know what your subject matter is, so this is the best I can do.  Toward the bottom of the page are puzzles on algebra, polynomials, systems of linear equations and inequalities.

Having excellent math skills and being able to block out distractions is the only sure-fire way.  No matter what anyone is saying, do the math in your head.
