Petek, you were correct! Thank you! I verified the solution with a collegue. I summed the values up to be 24887520

Sorry, No. There are 4536 numbers with each valuing above 1000. So, the SUM must be at least 4536,000 (BUT it is more!).

No, sorry. The digits of the numbers have to be distinct doing what you explained would be a lot easier though just use n(n+1)/2 from 1-10,000 and then again from 1-1000 and subtract the second from the first

No. Do it analytically please.

I need to find the sum of all 4536 numbers with distinct digits from 1000 to 10000 (so 4 digit numbers). Now, I developed a primary method for a solution but its too time consuming! anybody have any clever ideas?
