I know I'm a little late (and a valid solution has already been given), but no real explanation has been made. You first need to find a number that is a multiple of all these multiples (10 * 9, 9 * 8, etc), then one less than that will give the proper remainders. So, to find the least common multiple, first break these into primes:
10 * 9 = 2 * 3 * 3 * 5, 9 * 8 = 2 * 2 * 2 * 3 * 3, 8 * 7 = 2 * 2 * 2 * 7, etc.
Take out what is unique for each to get 2 * 2 * 2 * 3 * 3 * 5 * 7 = 2520. So, one answer (though you already know) to the original problem is 2519.

Yes[^], but then they "tweaked" it.

I figured the first post here should be made by a math major.

I was going to make a lame first post but I figured someone else deserved the honor :p

Heh. I'm actually an Applied Math/Computer Science major...so I'm screwed in both respects.

Sweeeeeet, a math forum
I'd like to help but I am too lazy to Google it for you.

No idea why anyone voted you a 1, maybe they don't like humour, anways to add to the list of pointless posts I'll inform you that I corrected that humourless "mistake".
As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it
