How it's used

Mathematical terms like this are often borrowed directly from written Chinese, so they sound formal even when used in a spoken sentence. You will mostly hear this in a classroom or academic setting rather than casual conversation. In everyday life, people rarely discuss number theory, so it is perfectly acceptable to use the English term if you forget the Cantonese one.
