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.

Examples

What is the result after taking the square root of this number?

Common phrases

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.
