My math book has this statement:
"Describe how to use a Ten-Thousand Square to round numbers to the nearest 1000?"
I don't really understand how to answer it.

Is this the answer?:
If the number in the thousands place is greater than 5, you round up. If the number is less than 5, you round down.

10,000 squared (10,000^2) is 10,000 times 10,000. Since the answer has only zeros, no rounding is needed.
Round up if the value is 5 or greater.
I hope this helps. Thanks for asking.
