1+2+3+4+5+6=21
if u add the lowest 6 digit numbers from 1 to 9 without repeating, the smallest number u can get is 21. so it can't be possible.

9/3 + 8/2 + 7 + 6 = 20

You can only do it using negative numbers, fractions, 0 or something other than base 10
-4 add 2 add 3 add 5 add 6 add 8 = 20
8/4 add 3 add 5 add 9 add 1 = 20
0 + 2 + 3 + 4 + 5 + 6 = 20
9 + 7 + 6 + 5 + 4 + 1 = 20 in base 16 (hexadecimal), works in other bases as well.

easy. do it backwards. subtract any digit from 1 to 9 from 20 until you get zero.

not possible ...
1+2+3+4+5 = 15 ..? already used them all ..
can't use 5 again to = 20 ?
and using 6 would equal 21 ..
ask a better question please :P~
