Central Otago Mathletics Competition<br />

This year two teams from each of Years 7-10 went to Cromwell College to compete in the Central<br />

Otago Mathletics Competition. Mathletics requires a combination of superb mathematics<br />

understanding, excellent computation and problem solving skills and the ability to work in a team.<br />

Some examples are given below - see if you can solve them! Our teams were pitted against the<br />

best from Dunstan High School and Cromwell College. We are proud of all our competing teams<br />

and would like to acknowledge the following great results:<br />
