  Does the hockey stick identity work when the "hockey stick" is placed horizontally?

  PS: I haven't proven or disproved it. Just a guess.

  Q

  @professionalbronco No worries about the bump! Super glad to see you learning so much, and even coming back to correct an old post 🙂

  You're absolutely right, these sums don't converge, so you can't manipulate them as if they were actual equations. In fact, \(1+2+3+4+...=-\frac{1}{12}\) is just really misleading in general. While \(-\frac{1}{12}\) is related to it, it's not really "equal" to it in the normal sense.

  Great job once again!

  In the video, when Prof. Loh was explaining the second way to do the pirates and gold coins problem, he only took away 8 choose 3. I thought you should take away all the different cases like 7 choose 3, 6 choose 3, etc. Why didn't he take away the rest? Thanks.
