Well, isn't that a happy little number! When we round 34821 to the nearest hundred, we look at the digit in the tens place, which is 4. Since 4 is less than 5, we keep the hundreds digit the same and change the rest to zero, giving us 34800. Just a gentle little adjustment to make everything feel just right.
