Oddtown may seem like a combinatorics problem! It has a town, people and clubs. But don't be fooled! It's a linear algebra problem!

Let us demonstrante another application of the Lagrange Multipliers and prove AM-GM!

We are building a bridge! A bridge to cross two fields of mathematics: Linear Algebra and Real Analysis.

Competing at the International Mathematics Competition.

Let's play football! Actually... Let's do math with football!

Sometimes people declare redundant axioms. Positivity is one of them.
