I really hope one day I will be back to do math but I gotta sustain myself for food and also have fun chatting here. It is really good complaining all day. Yeah I gave up math after I know I cannot even buy Ramen and have to save my money for internet to watch meme. What a loser have I become. I could instead answer question in mse but look how worthless have I become. I apologize to do this and not contributing to this community. My sincere apology. Take it or leave it.
