Here we should fully understand the characteristics of each number, such as 0, source, or their first son. I didn't think so much. I feel that 2-9 are almost the same, and 0 also has some characteristics. 1 multiplied by any number equals itself. Where 3, 5 and 7 are prime numbers and 2 is the smallest even number. You can talk about anything related to numbers.
But in the end, I still have to show my views and opinions. It should be a happy ending!
Small opinion, for reference only!
