How do you round 20562 to the nearest thousand?

0 is in the thousands spot, so that is what you round.

5 is behind the thousands spot, so you use that number to determine if you are going to round or not.

Remember that if the number is 4 or less, you don't round it.

Remember that if the number is 5 or more, you round it up.

So since 5 is roundable, you turn 5 and every digits below it to 0.

So now, the 0 that is in the thousands place rounds up to 1.

So the answer is: 21000
