November 18: Quick! Tell me what you get when you divide the number 992.587318, by 5,647.723? Stumped? Need a calculator? Well, thirteen-year-old Hiroaki Tsuchiya of Japan arrived at the answer in no time at a mental mathematics tournament in Kyoto: the right answer – 0.17575000013279688115015555826658. And, he did it without a calculator, too!

Hiroaki is adept at mental arithmetic multiplying, dividing, adding or subtracting large numbers that would make an accountant’s head spin. An Associated Press report that appeared in ‘The Asian Age’ says that Hiroaki is not the only one with such ability. For centuries, merchants, students and thousands of ordinary people throughout Asia have been calculating dizzying rows of numbers, using the same technique that Hiroaki has.
