Theoretically speaking, a lot of things could be solved if, going by what we learned in school, things are linear and getting from Problem A to Solution B would be so easy.
But in this world where all else isn't equal, you can't do that.

Do you think that you've ever solved a massive problem with what you've learned in school using an equation? (engineering aside)
it could be Economical, Political or just between a wife and husband
