Definition of Approximation | SubjectCoach

An approximation is a way of giving a measurement or an answer that is not exact but is close enough to be useful.

For example, you might round the length of a line segment from \(2.12 \text{ cm}\) down to \(2 \text{ cm}\).

If your height is \(165.4 \text{ cm}\), you might say that it is \(165\) and a half centimetres.

\(3.14\) is a useful approximation of \(\pi = 3.14159265\dots\), as is \(\dfrac{22}{7}\).
