The Mathematical Association of Western Australia has been organising student mathematics competitions for more than 50 years. Mathematics competitions allow students to gain valuable experience while developing their mathematical problem-solving skills in a friendly yet challenging environment. These collections of practice problems were compiled by the Mathematical Association of Western Australia. It is designed to help students prepare for competitions such as the Australian Mathematics Competition, Have Sum Fun and Have Sum Fun Online. These books contain over 120 practice problems arranged into 16 problem sets similar to those that students can expect to encounter in mathematics competitions at their respective levels.
