What are Place Values?
A place value is a digit in a number. For instance, in the number 742, the 7 is in the hundreds spot, indicating a value of 600. The convention in math is to work in a base-ten system. The system has unique symbols to represent the numbers 0-9. There is not any unique symbol representing 10 or a larger number, nor is there a unique symbol to represent any infinite numbers between 0 and 1.
