This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

@Krishna Ar, You should buy 'An Excursion in Mathematics'. It is a book specially for RMO. You may not be impressed by the cover & the page quality, but it includes everything except trigonometry. Believe me, it is thin, contains less than 250 pages (242 or so) & has many question papers. Only at Rs.160. Go on. Buy it.
Being only a teen, my brain cannot understand any of that as I mainly do fast to solve questions. Still, it was fun.
Easiest was probably the last question.
3/5
