Description: Sal compares the threes in 7,346,521.032 by considering their place value. Created by Sal Khan. And what I want to think about is if I look at the same digit in two different places, in particular, I'm going to look at the digit 3 here and the digit 3 here, how much more value does this left 3 represent than this right 3? So let's write down all the place values. And as we move to the right in place values, each place represents 1/10 of the place before it.
