The digit 0 has no value, but the place it holds in a number affects the value of the number as a whole.
Take a look at the number 5,030. It has a 5 in the thousands place, which means it has 5 thousands; a 0 in the hundreds place, which means it has no hundreds; a 3 in the tens place, which means it has three tens; and a 0 in the ones place, which means it has 0 ones.
