"Twenty-seven, twenty-eight, twenty-nine."
Translation:Veintisiete, veintiocho, veintinueve.
I accidentally typed "27, 28, 29" and it was accepted. Not sure if this has been the case for English-to-Spanish numbers all along, but they should change this.
I think when going from English numbers to spanish, yes they should not except written numbers, but going from Spanish to English, I don't think it should make a difference.
