rekenaarstelsel

Rekenstelsel refers to a system of representing numbers. Different cultures and historical periods have employed various rekenstelsels. The most common rekenstelsel in use today is the decimal system, also known as the base-10 system. This system utilizes ten unique digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The position of a digit within a number determines its value, with each position representing a power of ten.

Before the widespread adoption of the decimal system, other rekenstelsels were prevalent. The Babylonian civilization, for instance, used a sexagesimal (base-60) system, which is still reflected in our measurement of time (60 seconds in a minute, 60 minutes in an hour) and angles (360 degrees in a circle). Ancient Egyptians used a hieroglyphic numeral system, and the Romans developed their own system using letters like I, V, X, L, C, D, and M.

The concept of zero as a placeholder and a number in its own right was a significant development, originating in ancient India and later adopted by Arab mathematicians, who then introduced it to Europe. This invention was crucial for the advancement of arithmetic and algebra. Modern computers, however, operate using a binary rekenstelsel, or base-2 system, which employs only two digits: 0 and 1. This binary system is fundamental to digital technology. Understanding different rekenstelsels provides insight into mathematical history and the evolution of communication.
