These have the form a x 2 b x c. When squared it produces a four-digit number whose first two digits are the same and equal to the originals minus one and whose last two digits are the same and equal to the half of the originals. It is considered by many to be the most beautiful equation in mathematics. These were a collection of seven of the most important math problems that remain unsolved.
