My math book has this statement:

"Describe how to use a Ten-Thousand Square to round numbers to the nearest 1000?"

Is this the answer:

If there is a number higher than 5 in the thousands place then you round up, but if it is lower than you round down?

Yes, that's the rule for rounding, but I've never heard of "Ten-Thousand Square"...

To use a Ten-Thousand Square to round numbers to the nearest 1000, you can follow these steps:

1. Start with the given number you want to round.
2. Look at the digit in the thousands place.
3. If the digit in the thousands place is 5 or greater, you round up to the next higher thousand.
4. If the digit in the thousands place is less than 5, you round down to the lower thousand.

In your case, if there is a number higher than 5 in the thousands place, you round up to the next higher thousand. If it is lower than 5, you round down to the lower thousand.

For example, let's say you have the number 6,753. The digit in the thousands place is 7, which is greater than 5. So, you round up to the next higher thousand, which is 7,000.

Alternatively, if you have the number 4,812, the digit in the thousands place is 4, which is less than 5. So, you round down to the lower thousand, which is 4,000.
