Look at the digit all the way to the left and the one immediately to the right of it. If the one to the right is 5 or more, increase the one to the left by one and zero all the rest of the numbers. If the one to the right is 4 or less, leave the one to the left and zero all the rest.
In the number 3,400 the greatest place would be the 3. And in 800, the greatest place would be the 8. Basically it is the highest value in a number.
800
To round 44005 to the greatest value, you look at the digit in the thousands place, which is 4. Since the next digit (the hundreds place) is 0, you do not round up. Therefore, 44005 rounded to the greatest value remains 44000.

In the number 3,400 the greatest place would be the 3. And in 800, the greatest place would be the 8. Basically it is the highest value in a number.
Whatever the greatest place is, look at the number immediately to the right of it. If that number is 4 or lower, zero it and everything to the right of it out. If that number is 5 or higher, increase the greatest place by one and zero everything to the right of it out.
