Mathematicians long wondered whether it's possible to express the number 33 as the sum of three cubes — that is, whether the equation 33 = x³+ y³+ z³ has a solution. They knew that 29 could be written ...

A team of researchers, including a Google engineer, has produced a proof that shows that no initial Rubik's Cube position needs over 20 moves to solve. Prior to this, researchers had narrowed down the ...

The number 1729 may look ordinary, but a casual remark by Srinivasa Ramanujan turned it into a mathematical legend, ...

When you compare numbers, you find out which is bigger and which is smaller. You can use the words 'less than', 'greater than' or 'equal to' to compare numbers. Each phrase has a matching symbol that ...
