What is place value?

Place value is the basis of our entire number system. It is the value of each digit in a number. In other words, the position of a digit in a number determines its value.

For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000.
