Mathematical equation

guys a simple question that deserves an answer, i was good in math back in those days but now, got myself caught up in a different world that is occupied by the unnamed forces.

things just happen suddenly , you might not know the reason but believe me guys there most be some thing behind it, but to come to think of it, for once i use to think of maybe the way i see things were wrong, but on another hand though, you have to see things on different prospects, that will prevent a system brake down " ", which might mean different things entirely from what you are thinking.

you see this brain that we have is not just there to think of stuff like ....... and ...... , you know what i am talking about. but in order for a person to verify, the key is "Patients" and "presistance " in what ever we do.

now i got you thinking huh, think well and you will find out what the blank spaces are, and never see a situation in a single prospect, ask yourself "the what ifs", that do help but dont go to the extreme.

the equation:

(-ve) negative + (-ve)negative = ??????? (give me an answer i am to dumb)
