zero makes the numbers like mercury

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
