How it's used
Mathematical terms like this are often borrowed directly from formal written Chinese into Cantonese academic settings. While it is used in classrooms, speakers will often switch to English terms like "identity" when discussing advanced mathematics to avoid ambiguity. It is strictly limited to formal or educational contexts.
