Number theory on decent level. But no one expects the Spanish math problems to be easy. Oh, Spanish Inquisition too, yes 🇪🇸 Have fun with this 2013 Spanish Math Olympiad problem!

You can find a lot of different solutions to this problem and that’s what I love about it. Have fun! 🇮🇹

I wonder how many different solutions will you folks come up with 🤔 because this problem allows you to take many, many different paths! Bonus challenge: prove, that if a, b and c are all nonnegative, then a=b=c. Have fun! 🔥

🇵🇱 POLSKA GUROM 🇵🇱 Btw I haven’t seen factorial in an inequality problem for a while. And here it makes total sense. Especially when you connect it to a certain graph theory problem… enjoy! ❤️

Posed by the Legend himself, Titu Andreescu and Nikolai Nikolov, functional equation that will surprise you on every step towards the final solution. Enjoy! ✨

The equation itself suggests that there shouldn’t be that many pairs of such numbers, but what exactly are they? 🤔 That’s the question Nguyen proposed for Polish Math Olympiad, which stays to be a great place to find interesting math problems. Have fun! 🔥

Triangle 🔼 from another Triangle 🔺 Angles are the new Sides. So simple, yet so elegant! Don’t miss the additional task of finding out when these two triangles are similar. In my opinion it’s a great challenge to tackle. Have fun!
