Assalamu alaykum The net sum "Sigma" is same in all Madhabs. I don't mind following any madhabs of the locals where the scholars of my madhabs are not available. As I said earlier, wallahu aalam, may be it is the hikmah of Allah SWT that the net SIGMA is same Note: Sigma is the net sum of all the signed numbers (both positive and negatives) in a given array.
