Answer:
13,000
Explanation:
If you're rounding something to the nearest thousand, you are taking the closest number to that thousand (in this case it's 5) and rounding that number up or down, depending.
5 is closer to 10 than 0, so 5 becomes 10.
This means you make the place where 5 is 0, and add 1 to the next place over (which is 2).
So 2 + 1 = 3.
You turn every number before the 5 into 0, no matter what number it is.
So 13,098 becomes 13,000, which is your answer
