Well, isn't that a happy little question! When we round 98 to the nearest ten, we look at the digit in the tens place, which is 9. Since the digit to the right of it is 8, which is 5 or greater, we round up. So, 98 rounded to the nearest ten is 100. Just like that, we've created a beautiful rounded number!
