This is No. 2 of the ATOP EDUCATION Maths Challenges where we aim to get you all thinking. There will be problems for all levels of the school system, grouped in school grades. When you have an answer go to our email on the contacts page. Write the answer, your full name, school year and then phone number or email address. This is most important as otherwise we will not be able to send you a gift if you get it right.

Class Years 9 to 12
