Definition
指数 (zhǐshù) is a noun with two distinct senses: in economics/statistics it means 'index' (e.g., price index), while in mathematics it means 'exponent' or 'exponential'. Its sibling 指标 (zhǐbiāo) also translates to 'index' but refers to a specific target, quota, or indicator used to measure performance, not a general statistical index or mathematical exponent.
