To round whole numbers to the nearest ten, hundred, or thousand place, follow these rules:

1. Nearest Ten:
   • Look at the digit in the ones place.
   • If the digit is 0, 1, 2, 3, or 4, keep the tens digit the same and change all digits to the right to 0.
   • If the digit is 5, 6, 7, 8, or 9, increase the tens digit by 1 and change all digits to the right to 0.
2. Nearest Hundred:
   • Look at the digit in the tens place.
   • If the digit is 0, 1, 2, 3, or 4, keep the hundreds digit the same and change all digits to the right to 0.
   • If the digit is 5, 6, 7, 8, or 9, increase the hundreds digit by 1 and change all digits to the right to 0.
3. Nearest Thousand:
   • Look at the digit in the hundreds place.
   • If the digit is 0, 1, 2, 3, or 4, keep the thousands digit the same and change all digits to the right to 0.
   • If the digit is 5, 6, 7, 8, or 9, increase the thousands digit by 1 and change all digits to the right to 0.
