Digits are the basic symbols used in mathematics to represent numbers. The ten digits in the decimal system are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. These digits can be combined in various ways to create larger numbers, allowing for counting, measuring, and performing calculations. In addition to the decimal system, there are other numeral systems that use different digits, such as the binary system, which uses only 0 and 1. Digits play a crucial role in everyday life, from simple tasks like telling time to complex operations in fields like computer science and engineering.
