The Sumerians were able to create multiplication and division tables, cubes and cube roots. They were also able to calculate the area of a right triangle, a rectangle and divide a circle into 360 degrees. They would later put together some of the ideas that make up the Pythagorean theorem and quadratic equations.” ¹ “Sumerian mathematics was based on a sexagesimal or 60 number system that could be physically counted using the five fingers and 12 knuckles of one hand. Additionally, the system used place values where the digits written in the left column represented larger values. They had two distinct symbols to also represent ones and tens. This system was based on 60 because it was seen as the number with the most divisors. This idea has since been abandoned for the number system. Instead, we kept the divisor 60 to take time into account. For example, in a minute there are 60 seconds, in an hour there are 60 minutes, and so on. Later Babylonian tablets dating from around 1800 to 1600 BC have been found and cover topics of fractions, algebra, ways to solve quadratic equations, and cubic equations. Square figures and quadratic equations arose naturally when trying to make measurements. These tablets are said to give us our first look at quadratic equations. The way they solved these problems was by playing an unconventional game of cutting shapes and rearranging them. Today we use everything
