How it's used

People often use this when dealing with money or time to avoid being overly pedantic about exact figures. It carries a sense of flexibility, implying that the speaker is rounding off for the sake of convenience rather than aiming for scientific precision. It is common to pair this with verbs like 報 or 講 to request a rough estimate.

Examples

This number is just an approximation, no need to take it so seriously.

Common phrases

give an approximate figure
just an approximation

Common mistake

Learners sometimes confuse this with 概數, which is a more formal or academic term for approximate numbers. In casual daily speech, 約數 is the standard choice, while 概數 might sound slightly stiff or like a textbook definition.
