How it's used
Mathematical terminology in Cantonese often mirrors the structure of formal Chinese but is used freely in classroom settings. While it describes the specific operation of finding a square root, it is rarely used outside of academic or technical contexts. It is distinct from the common verb 開, which is used for opening doors or starting machines.

Common mistake
Learners often confuse this with 開方, which in a medical context can refer to a doctor writing a prescription. Context is essential to distinguish between a mathematical operation and a clinical instruction.
