How about 7*7/7*1+2+3-6+2

or 7+7/7+1-2+3+6-2=8
Those answers only work if you ignore order of operations. The only one I found was 7+7+7*1-2-3-6-2
dufus' works just fine using the order of operations as well.
There's lots of solutions, but seeing the last two numbers were 6 and 2, my first try was:
7/7/(7-1-2-3) * 6+2 = 8
7/7/(7-1-2-3) * 6+2 = 8
How about 7 + 7 - 7 - 1 - 2 * 3 + 6 + 2 = 8
Too many possibilities to be a challenge? A more interesting question would be 'how many solutions are there?'
