Can anyone in simple terms tell me what it is we are trying to solve with these problems and what a good first step is when seeing a variance question? To save time, yes I have wathed the Roger Youtube video, SEVen etc., I can memorize, but just haven't had that aha moment yet. Just need a little guidance, I will crack the rest myself with practice. Many thanks
