Would you please breakdown this sentence in its ¨pady¨? More precisely why isn't it ¨Je matematika takÝ technický obor?¨
matematika - nominative feminine?
obor = accusative masculine?
what are také and technický?
This is just an "X is Y" sentence. Everything is nominative. Word taký does not exist in Czech. Také (or colloquially taky) is an adverb meaning "too, as well", it does not have any cases. Technický is a hard declension adjective (like velký).
