Best ResponseYou've already chosen the best response.0I'll give you a clue: What you DON'T want to do is find all the permutations, write them down, then sum them.

Best ResponseYou've already chosen the best response.0hey, there are 6! of sixdigit numbers ( 720 numbers ). The point is not to find a sum, but to find an easy way to find that sum.

Best ResponseYou've already chosen the best response.0That's what I was getting at (i.e. look for an easy way, do not do it). So you know there are 720 permutations  that's a good start. What can you say about the number that have "1" in the first position? What about "2"? What about the numbers in the next position? Think along those lines.

Best ResponseYou've already chosen the best response.0also, what does a '1', '3' etc in the first position mean (as opposed to, in the last)

Best ResponseYou've already chosen the best response.0The answer is not going to be 5!. 5! is 120, which is a lot less than any permutation of of 123456 (assuming I understand the question right)

Best ResponseYou've already chosen the best response.0I did i on this way: 5!(100000 + (2+3+4+5+6)*10000 + (2+3+4+5+6)*1000 + (2+3+4+5+6)*100 + (2+3+4+5+6)*10 + (2+3+4+5+6)) + 5!(200000 + (1+3+4+5+6)*10000 + (1+3+4+5+6)*1000 + (1+3+4+5+6)*100 + (1+3+4+5+6)*10 + (1+3+4+5+6)) + 5!(300000 + (1+2+4+5+6)*10000 + (1+2+4+5+6)*1000 + (1+2+4+5+6)*100 + (1+2+4+5+6)*10 + (1+2+4+5+6)) + 5!(400000 + (1+2+3+5+6)*10000 + (1+2+3+5+6)*1000 + (1+2+3+5+6)*100 + (1+2+3+5+6)*10 + (1+2+3+5+6)) + 5!(500000 + (1+2+3+4+6)*10000 + (1+2+3+4+6)*1000 + (1+2+3+4+6)*100 + (1+2+3+4+6)*10 + (1+2+3+4+6)) + 5!(600000 + (1+2+3+4+5)*10000 + (1+2+3+4+5)*1000 + (1+2+3+4+5)*100 + (1+2+3+4+5)*10 + (1+2+3+4+5))

Best ResponseYou've already chosen the best response.0Erm, do you know what that comes out to in total? I did pretty much the same, but did it all in one go, rather than splitting the 100000s etc form the rest

Best ResponseYou've already chosen the best response.01+2+3+4+5+6 = 21 Sum = 21 * 120 + 210 + 120 + 2100 * 120 ...... + ..... + 2100000 * 120 = 120 * 21 * 111111 = ....

Best ResponseYou've already chosen the best response.0sorry, the second line has a typo: it should be 21 * 120 + 21 * 10 * 120 + 21 * 100 * 120 .... + ..... + 21 * 100000 + 120
