Whole numbers are made up of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This system is the decimal system because the word “deci” is taken from the word “decimus” (latin) for one 10th. Therefore, there are ten digits that make up this system. Please know that there are other numbering systems (binary, hexadecimal, etc.), however this website will only discuss numbers in the decimal system.

The value of each digit is different because of its position in the number. Every position has a place value. The table below gives the names of some of the places in our number system. Example 1:
