I am very confused. I don't know what a necessary or sufficient condition is. Is it sufficient if it says the word "all" always? And if so what does that mean? So the sufficient conditions are the ones with the 'all' and the necessary condition is what the sufficient conditions are combined? Or what they result in? I am so confused.
