- The Place Value of a digit is based on what place or position it occupies in a number
- Example: The Place Value of 3 in 437 is 30 since 3 occupies the Tens place and 3 * 10 = 30
- Because there is no single digit in the base-10 numbering system greater than 9, the value of each place is 10 times greater than the value of the place to its immediate right
- Example: A 2 in the Hundreds place has a value (200) that is 10 times greater than the value of a 2 in the Tens Place (20), and the value of the 2 in the Tens place has a value 10 times greater than the value of a 2 in the Ones place (2)
- Application: Expressing a number in expanded form
