Every year, the countries competing in the International Mathematical Olympiad arrive with a booklet of their best, most ...

Little progress had been made in solving Ramsey problems since the 1930s. Now, researchers have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades.

Fourth grade math doesn’t have to be worksheets and groans — it can be full of games, real-world challenges, and creative projects that spark curiosity. From multiplication bingo to problem-solving ...

Ramsey problems, such as r(4,5) are simple to state, but as shown in this graph, the possible solutions are nearly endless, making them very difficult to solve. We’ve all been there: staring at a math ...
