Translation:One hundred, two hundred, three hundred, four hundred, five hundred, six hundred, seven hundred, eight hundred, nine hundred, one thousand
This "sentence" should be split into at least two or three parts. Maybe it's even possible to use the numbers in a context. ;)
The numbers lesson as a whole should be looked at again because of this, in my opinion. There has to be a better way to learn numbers in Esperanto than banging out 100+ characters to ultimately just count to ten.
