Ready to solve some puzzle?.. If not you gotta try, if you are ready then I dare you to solve this… — Today’s puzzle is a bit wordy but the solution is very elegant. The object of this puzzle is to place the largest possible number of coins at points of the eight-pointed star depicted in the table below. The coins should be placed one after another, with the following restrictions: A…

Now you know derivatives and integrals. What is next? There are still a lot of topics you will familiarise yourself with, at least if you want to pass AP Calculus BC. But here is one of them: Integration By Parts. Wait… What does that even mean? Let me explain with…

Ready for some brain gymnastics? Let’s start. — There are eight identical-looking coins; one of these coins is counterfeit and is known to be lighter than the genuine coins. What is the minimum number of weighings needed to identify the fake coin with a two-pan balance scale without weights?

Roses are red, but life is not blue… — So this is my first, not math-related topic but I am pretty sure that it is not the last. How can I be so sure? Because I changed my direction and adjusted my life a little bit. As a result, this story will tell you how you can do it…

A very entertaining way to solve problems which seems hard otherwise… — A Simple Search… Let’s have a look at some easygoing questions which you can solve by trying every possible case. But we should find more efficient solutions to those questions. You know what I mean… Rather than counting by fingers, we are going to find a solution which would give the direct answer…

Such an impressive way of handling hard problems in geometry! — Definition Given two circles ω1 and ω2 with distinct centres, the radical axis of the circles is the set of points P such that, Powω1 (P) = Powω2 (P). This might seem rather confusing definition as P seems to be a phantom point. …

Temmuz ayının sorusu ile karşınızdayız. — Bu ay, geçen aydan farklı olarak bir sonlu matematik sorusuyla değil, bir sayılar teorisi sorusuyla karşınızdayız. Sorumuz oldukça kısa: a ve b tamsayılar olmak üzere (a² + b² + 3)/ab ifadesinin tamsayı olmasını sağlayan tüm (a,b) tamsayı ikilileri nelerdir? Sorunun cevabını 1 hafta sonra yayınlanacak olan cevap videosunda ve Medium sayfamızda yayınlayacağımız makalede bulabilirsiniz!

Bu makalede Temmuz ayının sorusunun çözümünü inceleyeceğiz. — A² + b² + 3, ab ye bölünecek şekilde kaç (a,b) tamsayı ikilisi vardır? Şimdi önce negatiflik, pozitiflik durumuna bakalım. Eğer bir (a,b) ikilisi şartı sağlarsa, (-a,b), (a,-b) ve (-a,-b) de verilen şartı sağlar. Bundan dolayı sadece pozitif (a,b) ikililerini bulsak yeter. …

Two outstanding solutions in a mindblowing competition: International Mathematical Olympiad — IMO (International Mathematical Olympiad) is a competition to which a lot of high school students from different countries attend.
