The place value tells you the value of each digit in a number. In our numeration system, the digits that we use are any of the symbols 0,1,2,3,4,5,6,7,8,9. The value of a digit or each place is equal to 10 times the value of the place to its right.
Notice that each number has a place and a value, thus the name place value. The first place on the right has a value of 1. The second place from the right has a value of 100. The third place from the right has a value of 100, and so forth...
