They used symbols to represent numbers and were the first to use place value, which allowed for the representation of larger numbers.

The Egyptians, around the same time, used a system consisting of hieroglyphic symbols, which also incorporated place value. However, they had separate symbols for tens, hundreds, thousands, and so on.

The ancient Greeks made significant contributions to the development of fixed numbers. Pythagoras and his followers believed that numbers were the building blocks of the universe and viewed them as fundamental entities. They explored the concept of perfect numbers, which are fixed numbers that are equal to the sum of their divisors. Euclid, known for his work in geometry, also contributed to the understanding of fixed numbers.

The concept of fixed numbers continued to evolve over the centuries, with Arab mathematicians making remarkable advancements during the Islamic Golden Age. They introduced the Hindu-Arabic numeral system, which is still used today and revolutionized mathematics globally.

Understanding the historical context of fixed numbers provides insight into how this concept has developed and shaped mathematical thinking throughout civilization.
