only multiplying, divisions, + and -. You can also use these ( ).

No composed numbers, so
888 + 88 + 8 + 8 + 8 = 1000
is wrong.

(8 * 8 * 8) + (8 * 8 * 8) - 8 - 8 - 8 = 1000

There are loads of ways of solving this one...
(8*8*8) + (8*8) + (8*8) + (8*8) + (8*8) + (8*8) + (8*8) + (8*8) + 8 + 8 + 8 + 8 + 8 = 1000

Sorry I was a moro(n/s). You can only use the number 8 eight times.

In 7:

(8 + 8)*8*8 - 8 - 8 - 8 = 1000

EDIT: Unless you mean I have to use it 8 times. Give me a sec...

In exactly 8 8's:

(8*8 + 8*8)*8 - 8 - 8 - 8
