Approximating with sequential numbers

Expressing approximate numbers in Chinese is quite simple, and this article introduces one of the most basic ways to do so.

Structure

An easy way to express approximate numbers is to use two sequential numbers in a row.

Number + (Number + 1)

This is similar to saying "x or y" or "about x" in English.
