About
The word 倒数 (dàoshǔ) is formed by combining two characters: 倒, meaning "to reverse" or "to invert", and 数, meaning "to count" or "number". Literally, it conveys the concept of "counting backwards" or "reverse numbering". This formation visually and conceptually captures its dual meanings: the mathematical reciprocal (the "inverted" number, like flipping 2 to ½) and the act of counting down in sequence (3, 2, 1...), both stemming from the core idea of inversion in order or value.
