Hello Codeforces!
We will be having Round 3 and 4 of MathMash today and tomorrow respectively, both at 15:00 UTC.
The rounds will consist of 8 problems to be solved within 2 hours.
The points distribution for today's round are decided as follows for now: 500, 750, 1000, 1500, 2000, 2500, 2500, 3500.
You're all invited to join the contests. Hopefully we'll have some fun and successful rounds.
PS: We need more collaborators in the problem setters team to help us set up more interesting problems. Four awesome people from Codeforces have already offered us their help :) I am really thankful to them. If you're willing to help us out, kindly PM me.

I apologize for the previous round's(Round 3) problem's quality. We misjudged their elegance and difficulty.
I hope the participants enjoyed today's round and had a fun time with the problems. We are continuously looking for ways to further improve the site.
And also many congratulations to our first ever MathMasher Master(Yellow) rkm0959 who (again) solved all of the problems, just under an hour :)
