Many students are anxiously awaiting the robots for our ASA. In the mean time, we are working with variables, loops and conditionals by answering questions on ProjectEuler.net

The problem solved this week: what is the sum of all the multiples of 3 or 5 which are less than 1000?

Grades 11 and 12 Mathematics SL students should try solving this problem without a program (use a arithmetic series)
