A nonzero digit is a numerical digit that is not equal to zero. A digit is a numerical symbol that represents an integer from 0 to 9, so a nonzero digit is any digit from 1 to 9.
Digit values are used in combinations to create representations of larger numbers. For instance, the digits 5 and 0 can represent the integers of 5 and 0 respectively, or they are capable of being combined to represent the number 50. European digits, utilized primarily in Western countries, originate from the West Arabic system. In fact, most major languages have their own digit systems, such as the formal Chinese, Assamese Bengali and Ethiopian Ge'ez systems.
