A number system which uses digits from 0 to 9 to represent a number with base 10 is the decimal system number. The number is expressed in base-10 where each value is denoted by 0 or first nine positive integers. Each value in this number system has the place value of power 10.

decimal system, in mathematics, positional numeral system employing 10 as the base and requiring 10 different numerals, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. It also requires a dot (decimal point) to represent decimal fractions. In this scheme, the numerals used in denoting a number take different place values depending upon position.

Base 10 Number System Base 10 number system uses digits 0 to 9 to represent numbers and thus has a base of 10. It is commonly known as the decimal number system. The English name was derived from the Latin word ‘decimus’, which means ‘tenth.’ Mathematically, it is written as (2,145) 10.

Base 10 is a method of assigning a place value to numbers. It's also known as the place value number system, or decimal system, as the numerical value of a number relies on where the decimal point sits. In base 10, each digit in a position of a number can have an integer value ranging from 0 to 9 (10 possibilities).

Decimal Number System (Base 10) The decimal number system consists of digits 0 to 9 with a base of 10. Here, the first few successive places left of the decimal point represent units, tens, hundreds, and thousands. It is the number system we commonly use in real life. 45 10, 289 10, and 5781 10 are examples of decimal numbers.
