Two students have won top awards in the Australian Mathematics Competition. Andy Wong, a Form Three student at Pui Ching Middle School, was awarded a medal, while schoolmate Hui Yi-kai, a fifth former, won a prize. According to the Australian Mathematics Trust, organiser of the competition, just one in 10,000 contestants is awarded a medal and one in 300 wins a prize. Andy's interest in maths started in primary school. 'I found it very challenging. The pleasure of tackling a particularly difficult problem is hard to describe,' he said. Because of his interest in the subject, even going to the supermarket with his mother was fun, he said. 'I would help my mother do the calculations, and I would have to be faster than the machine,' he said. Yi-Kai enjoyed maths for a different reason. 'It is the foundation of all science subjects,' he said. 'Almost all problems in science can be solved by mathematics.' While basic concepts were important, constant drills helped improve the skills needed to solve mathematical problems, he said. Another 85 students were awarded certificates for distinction and high distinction. More than 500,000 students from the Asia Pacific region - 1,600 of whom were from Hong Kong - took part in the competition. Five students posted perfect scores - two from Taiwan, one from Singapore and two Australians.
