You know that game 6 degrees of separation, where you find 6 people you and a stranger have in common? You can do the same thing with your job and MIC spending by the government.
Right, but if you look in the field of probabilities, specifically when expanding binomial distributions, you go increasing powers with one and decreasing powers with the other.
ax^4 + bx^3y + cx^2y^2 + dxy^3 + ey^4
That’s why it makes sense to me to read it a^2 + 2ab + b^2
