Ah, let's see here, friend. When we round 810 to the nearest ten, we look at the digit in the tens place, which is 1. Since 1 is less than 5, we keep the tens digit the same, and change the ones digit to zero. So, 810 rounded to the nearest ten is 810. Just a little adjustment, but it can make a big difference in how we see things.
