- 9 is in the tens place and 9 is in the ones place
- Since the digit in the ones place (9) is greater than or equal to 5, add 1 to the digit in the tens place (9)
- 1 + 9 = 10, so the digit in the tens place becomes 0, and 1 is added to the digit in the hundreds place (0)
- 1 + 0 = 1, so the digit in the hundreds place becomes 1
- 0 replaces the (9) in the ones place
- 1,099 rounded to the nearest ten = 1,100
