Problem of the week
A new olympiad problem every Monday, with three hints you can open one at a time, the way a tutor would give them.
What is 1 + 2 + 3 + … + 19 + 20?
- Adding one by one is slow. Try pairing numbers from the two ends of the list.
- 1 + 20 = 21, 2 + 19 = 21, 3 + 18 = 21 … every pair makes the same total.
- Twenty numbers make 10 pairs, and each pair is 21.
Show the answer
10 pairs of 21 make 210.
Build your own test
Choose a grade, tick any topics from the five chapters, pick 5 to 25 questions, and get it marked on the page with working for every question. Fresh questions every time.
Olympiad problems with hints
70 hand-picked problems, plus a fresh problem whenever you want one: 169 kinds of question from past olympiad papers, each with new numbers every time, a three-step hint ladder and a worked solution.
