Arithmetic Wonders: How Ancient Civilizations Used Math in Remarkable Ways

Arithmetic has been a cornerstone of human progress, and throughout history, ancient civilizations have employed mathematics in astonishing ways. From the construction of monumental structures to the development of innovative numeral systems, arithmetic has played a critical role in shaping the world as we know it. In this blog post, we'll delve into some of the incredible ways ancient civilizations utilized math.

The Sumerians and the Sexagesimal System

The Sumerians, who lived in ancient Mesopotamia, developed the sexagesimal (base-60) numeral system around 4,000 years ago. This system is still used today to measure time, angles, and geographic coordinates.

Egyptian Mathematics and the Pyramids

The ancient Egyptians were renowned for their mathematical prowess, which they used to design and construct remarkable structures like the Pyramids of Giza. They developed a decimal system, hieroglyphic numerals, and methods for solving complex problems in geometry and arithmetic.

Greek Geometry and the Golden Ratio

The ancient Greeks made significant contributions to the field of mathematics, particularly in geometry. The Golden Ratio, a fascinating number approximately equal to 1.618, appears in various aspects of nature, art, and architecture. Greek mathematicians like Euclid and Pythagoras explored the properties of the Golden Ratio and its connection to geometry.

Mayan Mathematics and the Concept of Zero

The ancient Mayans developed a highly sophisticated numeral system that included the concept of zero. Their vigesimal (base-20) system allowed them to perform complex arithmetic operations and make accurate astronomical observations.

The Abacus and the Art of Ancient Calculation

The abacus, an ancient calculating tool used by various civilizations such as the Babylonians, Egyptians, Greeks, Romans, and Chinese, revolutionized the way people performed arithmetic operations. With its simple yet powerful design, the abacus allowed users to perform addition, subtraction, multiplication, and division efficiently.

The only flag of the world that is shredded by design

If you have played Kobadoo Flags you might have seen some extravagant flags with colourful designs, but you might not have seen before a flag made of separate strips of cloth. This is the case of the flag of Zamora , a beautiful province in the North West of Spain close to the border with Portugal. This flag is not only truly original, but as well one of the oldest in the world. It is composed of a green strip and eight red strips , all of them detached from each other. The red ones represent the eight victories obtained by the legendary warrior Viriathus against the Romans in the 2nd century BC. The green strip was a reward from King Ferdinand II of Aragon in recognition of the aid provided in the battle of Toro in 1476. Source: common.wikimedia.org
