simple grouping system

A numeral system is a set of symbols and rules used to represent numbers, which indicate the quantity of items in a set. Early systems, like those in Egypt and Greece, used simple grouping where symbols were repeated to represent numbers, such as using three strokes for the number three. As societies became more complex, the need for more sophisticated systems arose.12

A simple grouping system assigns names to small numbers and their powers (e.g., 1, 10, 100). Intermediate numbers are formed by repeating symbols, similar to how Roman numerals represent numbers. For example, the Egyptian hieroglyphic system was a simple grouping system.2

In contrast, multiplicative systems assign names to numbers from 1 up to the base and also to the base itself and its powers. These are then combined to form numbers. The most common system today is the Hindu-Arabic decimal system, which uses place value and ten symbols (0-9). This system, originating in India, was perfected and spread through the Arab world, becoming a near-universal language for mathematics.314
