I was just asking only alright to make sure of it, no harm. Even if it is very simple to you, do you think it is simple to me? now this reply of yours pissed me off okay?

btw thanks for your help I don't mean to be rude, if I know how to solve this question, I wouldn't have waste my time asking here and you would not waste your time helping me to solve this question correct or not?
