We know that the decimal system consists of 0 ,1 ,2 ,3 ,4 ,5 ,6 ,7 ,8 ,9. also we know that from x digits we can get X ! different numbers for instance from 4703 we can get 4! = 4 x 3 x 2 x 1 = 24 number
this numbers are :
0347 ، 0374 ، 0437 ، 0473 ، 0734 ، 0743
3047 ، 3074 ، 3407 ، 3470 ، 3704 ، 3740
4037 ، 4073 ، 4703 ، 4730 ، 3407 ، 4370
7034 ، 7043 ، 3704 ، 7340 ، 7403 ، 7430
Also we know that we can get from x digits x^x numbers (different and similar) for instance 4703 we can get 4^4 = 265 number
now from 4703 i can make :
- Smallest number consists of four digits = 0000
- Smallest number consists of four different digits = 0347
- biggest number consists of four digits = 7777
- biggest number consists of four different digits = 7430
- biggest odd number consists of four different digits = 7403
- biggest even number consists of four different digits = 7304
- smallest even number consists of four digits = 0000
- smallest number consists of four digits not equal zero = 0003
- smallest number consists of four digits bigger than 1000 = 3407
- biggest number consists of four digits smaller than 1000 = 0743
now you can make more by use zero then there is nothing wrong when I say zero makes the numbers like mercury
