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.

@Bogdan Simeonov @Sharky Kesa After Triple-checking, there IS a problem in question 2, we are terribly sorry and we have edited the question. @Finn Hulse You might want to resubmit for question 2 as well since you already submitted

The proof problems were a bit strange. No casework, no induction, not really much of anything! :P

Really? Last weeks for me was the easiest, this one for me was moderately tough.

I am a problem writer at JOMO but i also feel that this one is easier than previous JOMO (of course feeling easy/difficult may differ among people) .... Go on , all the best ! Progress expected this time .......

I didnt attempt any of the contest. If u are saying of the previous combinatorics contest, then I admit my worst prepared topic is combinatorics, while my strongest topic is inequalities.. But, previous contest was also easy, but I didn't get a few. As for this contest, I got all ques but one till now.. R u taking in it? all the best then

For question 2, I can't find any non-negative integer solutions for xx, yy and zz. Did yours have any negative numbers?

@Yan Yau Cheng I got a non-integral answer and I'm sure it's right...

@Finn Hulse It asked for nonnegative integers. I got two solutions for the equation but both of them had negative integers.

Sharky Kesa - 5 years, 6 months ago

I've told all of my friends! This is going to be really fun but @Yan Yau Cheng could you go a little easy on the trig? After all, this is Junior. I just finished. :D

@Nanayaranaraknas Vahdam The 1st equation was previously xy+2x+3y=2 but it was supposed to be xy+3x+2y=2 so we've edited it now
