Hello /sci/ bros,
I am trying to quit videogames and porn and I have been learning math from scratch for the past month. I came across to this thing: (a + b)^2 and (a + b)^3. I can think of physical things when I think of a^2 + 2ab + b^2 which is (a+b)^2. However when I think of a^3 + b^3 + 3ab(a+b) which is (a + b)^3, I cannot think of physical things for it to relate. I am a little concerned that I might be retarded. Is it normal if I can't think of physical things about it bros?
