9999 ÷ 10 = 999.9 Or 999 remainder 9
You can round up 999 to the nearest tens (that is 1000). This is only applicable when you are doing a calculation involving very huge value, where using 1000 or 999 will have negligible effect on the final answer.

It is 999, exactly as in the question.
To the nearest thousand, 57000
1,000
It is: 1,000
To the nearest tens, it is 1000. However, looking at the answer, it is not possible to tell whether it is a number rounded to the nearest hundred or thousand.
Well, isn't that just a happy little question! When we round 999 to the nearest thousand, we see that it's closer to 1000 than it is to 0. So, we round it up to 1000. Just like adding a little touch of paint to finish a beautiful landscape, rounding 999 to 1000 helps us see the big picture in a simple and clear way.
