Ancient Egyptian Inventions in Mathematics &Geometry Ancient Egyptians are credited with many mathematical innovations that laid the foundation for modern mathematics. Some of their notable inventions in this field include: 1. Hieroglyphics: The ancient Egyptians developed the hieroglyphic system of writing, which allowed them to record and preserve important mathematical ideas and concepts. Hieroglyphics also served as a way of communicating numerical values. 2. Fractions: The Egyptians were the first to use fractions in their mathematical calculations. They used a system of unit fractions, where the numerator is always 1, to perform complex arithmetic operations. 3. Geometry: The Egyptians pioneered the use of geometry in their architecture and engineering projects. They used geometry to build pyramids, temples, and other structures that required precise measurements and calculations. 4. Calendar: The ancient Egyptian calendar was based on the movements of the sun and the stars. They used a 365-day solar calendar and a 12-month lunar calendar to keep track of time. 5. Zero: The Egyptians were also the first to use zero as a placeholder in their mathematical calculations. This greatly enhanced their ability to perform complex arithmetic operations and helped lay the foundation for modern mathematics.

The ancient Egyptians are credited with several major contributions to the field of geometry, including: 1. Pyramids: The engineering of the complex geometric structure of pyramids is a testament to the Egyptian’s knowledge of geometry. They understood angles, symmetry, and measurement, which allowed them to build such complex shapes. 2. Geometry symbols: The ancient Egyptians used hieroglyphic symbols to represent geometric shapes and angles. These symbols were used in architectural plans and in measuring land areas. 3. Circle calculations: The ancient Egyptians were able to accurately calculate the circumference of a circle, which allowed them to measure the size of irrigation fields. 4. Rectangular shapes: The Egyptians made use of rectangles in their building designs, which were based on geometric principles. They used rectangles to provide support for columns, walls, and doors. 5. 3-4-5 triangle: The ancient Egyptians understood the concept of the 3-4-5 triangle, which is a right triangle that has sides in the ratio of 3:4:5. This knowledge was used in construction to ensure that corners were square. Overall, ancient Egyptian contributions to geometry laid the foundation for modern-day mathematics and architecture. Their understanding of shapes, angles, and measurements set the standard for engineers and architects for centuries to come.
