Less than that question everything being said. You have a right to question what appears to be out of reach intellectually and when in the presence of a true expert they will gladly re-frame and explain. A lesson to remember is if a person cannot easily explain a concept they tend not to have a total grasp and are far from mastering it. One of my personal favorites, that had a mastery of this art, was Richard Feynman. The greatest minds had the ability to distill concepts into a context that the most rudimentary layperson could grasp. I have seen many occasions when engineers over complicate a problem using difficult vernacular and when pressed to distill into common terms seem challenged. You are capable of understanding some very complex issues/problems when they are distilled into simple understandable concepts. It is about questioning things on face value for being beyond our capabilities. What lesson can we learn from this exercise? If we are not connected feel free to request a connection so I can send you the solution. If you would like it earlier please like, comment or share the post and I will send you the answer.
I will post an update in a week with the answer. With a little work you should be able to discover the 10th unique representation.
