Explanation
After nineteen we say twenty. We count in tens: 20 is twenty, 30 is thirty, 40 is forty, 50 is fifty, 60 is sixty, 70 is seventy, 80 is eighty, 90 is ninety and 100 is one hundred. To say a number in between, add the small number: twenty-one, thirty-five, sixty-two. Listen carefully: thirteen and thirty sound a little the same, but thirty is bigger.
