Despite the greatest strides in mathematics, these hard math problems remain unsolved. Take a crack at them yourself.

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.

Among high school students and adults, girls and women are much more likely to use traditional, step-by-step algorithms to solve basic math problems – such as lining up numbers to add, starting with ...

Math has a certain logic to it. If you use it to accurately describe a situation, sometimes you can predict the inevitable — for instance, the moment an eclipse will take place — centuries in advance.
