-646; because when you do the numbers in parenthesis (6-7) the answer would be - 1 because a positive being subtracted by a higher negative would be negative, the same vice versa. Then you would need to multiply it by two because that is the first number of multiplication, which would give you - 2. You would then need to multiply - 2 by 89 since that is the next number of multiplication, which would give you - 178. you would then need to subtract 468 from - 178, giving you an answer of - 646
