How is decimal notation expressed in computing?

Decimal notation in computing is expressed by each digit being assigned one of ten values from 0 to 9. This system represents numerical values using ten distinct symbols, which are the digits we commonly use in everyday life. The ten symbols allow for the construction of any given number, with each digit's position indicating its place value based on powers of ten.

For instance, in the number 345, the '3' is in the hundreds place, the '4' is in the tens place, and the '5' is in the units place. Therefore, this method of representation directly aligns with how the decimal system functions in mathematics and is fundamental for data representation in computing scenarios.

The other options misrepresent how decimal notation operates and involve concepts that pertain to different numbering systems or misinterpret the base system typically associated with decimal notation.
