Oh really then most of student in my center got a negative answer in (i) - (ii). I know shouldn't be negative but it was. -.-

NO problem ecf method is there so only one mark for sure would only be deducted mine was also negative but when I discussed it with my teacher he told me this so no need to be worried

No definitely positive for me and logically it has to be positive, you made a calculation mistake. and this value is used in other parts.

only one mark would be deducted because of ecf method so no worries
