Magical law of numbers
The world of numbers is full of magic, and some numbers have wonderful laws hidden behind them. For example, if a number is 100, subtract its single digits to get 80, but in fact we only use its first two digits, namely 8 and 0, and the last number 6 corresponds to the previous 8 and 0, and the result is 206!
The story behind the numbers
Each number has its own uniqueness and there are interesting stories behind it. For example, 1 stands for the beginning and the end, so it is your own answer: 1. 2 is a continuation of 1, so it is equal to 1 plus 1: 2 (1+ 1). 3 is a continuation of 2, so it is equal to 1 plus 2: 3 (1+2). The continuation of 4 is 5, so it is equal to 2 plus 3: 4 → 5 (2+3).
