In the past there were many legacies that changed today's' life. A lot of theories were formed and proven wrong, but they laid a base. In the same way, many inventions proved to be very significant. Cuneiform is the first ever form of writing in history and its significance is that from this writing originated all other different types of writing, which are used nowadays, to keep several records of various things, write history and to do other important things. Another significant legacy is the development of Mathematics in Ancient Greece. The construction of Pyramid is a legacy as no one, in modern days, was able to build something even close to the ancient Egyptian pyramids.

In Ancient Greece Mathematics developed a lot, and during that time loads of philosophers emerged. The Greeks received a lot of inspiration from the Babylonians. The merchants of Greece, being very good at business arithmetic, became teachers of this subject all over the world.

Pythagoras is described as a pure mathematician and is a very important person in the development of Mathematics because he was the one who came up with the Pythagorean theorem. His teacher Thales directed his attention towards Mathematics. Pythagoras and his fellow students were not intending to find a formula to solve mathematical problems when they found out the Pythagorean theorem. The Babylonians knew the Pythagorean theorem for thousandths of years but Pythagoras was the first one to prove it. Now a day's people are able to apply and state the Pythagorean theorem. It has had a great significant impact in the world of Mathematics and is used in everyday life as well. The Pythagorean theorem stated, " In a right angled triangle the area of the square on the hypotenuse is the sum of the...
