Mathematics is full of difficult problems, but the hardest math problem in the world is not just a difficult school test question: it is a question that challenges centuries of logic, calculation and creativity.
Some of these problems—spanning concepts from geometry to algebra to real-world analysis—involve seemingly simple equations, while others require an understanding of infinite sequences, graph intersections, or functions on the complex plane.
They require an understanding of how a function satisfies conditions, how values correspond to different dimensions, and how sequences evolve. The challenge is to prove that the solution is valid for all values, functions and variables in the mathematical space.
Here is a list of the most mind-blowing unsolved problems and legendary puzzles in mathematics.
