Q:
# Who invented integers?

**Integers, or numbers not represented as a fraction, such as 1, 2, 3 and so on, were not invented but rather discovered.** As a very basic component of mathematics, integers have been studied and worked with for longer than other mathematical discoveries.

However, the notation for integers and their symbolic representation has undergone many changes. The most commonly used symbols for integers are termed Hindu-Arabic numbers and have their origins in ancient India. They were adopted by the Arabic world and eventually replaced the Roman numeral system in Europe. The ability to use 10 symbols in combination to make every possible number makes the Hindu-Arabic system an efficient and easy-to-learn system of notation.
