@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!
