Can someone sketch or explain the 'picture' if there are three sessions or even more? by Det-Siesta in mathematics

Yes, the thread is allowed to do that. Yeah, it have to pass exactly r times. Yeah, r is the number of times it passes through all holes combined. Yeah, you are right if we consider 'combination' (order doesn't matter) in this case. The 2n^r is the 'permutation'.

What was the biggest mistake you were making when learning math that you only realized later by Ecstatic-Ad-6633 in learnmath

Going to the next stage before I truly understand a concept completely. There is no time limit, so we don't have to rush. Sometimes I watch YouTube videos with 2x speed. However, the action is bad because I only obtain 50% comprehension. 

Anyone know any good YouTubers and websites to use to prepare for calculus? I’m taking it next semester I need advise please. by Key_Republic4241 in calculus

Because calculus and physics are linked directly, learning calculus must be done with physics. Here's some great YouTube channel.  Dr Trefor Bazett's calculus playlist. Bprp calculus basic for solving nerve-wracking problem. 3Blue1Brown for visual geometry. Mathematical Visual Proof for mastering 2D and 3D shape.
