Re: sum of 4 digit no.

Hi juan;

the different four-digit number

What do you mean different?


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: sum of 4 digit no.

Hi;

Sorry, I still am not understanding. You want all the 4 digit numbers from 1,2,3,4,5? And then you want the sum of the numbers or the sum of their digits?
