What number comes after 19 (nineteen)?

• 11 (eleven)

• 20 (twenty)

• 29 (twenty-nine)

• 10 (ten)

Answer explanation

When we add a 1 to the ones place that contains a 9, it becomes 10. Since we cannot have a 10 in the ones place, we carry over that 10 into the tens place by going up 1 digit in the tens place. That is why the next number after 19 is 20.
