- This video develops the Double-And-Add Algorithm entirely intuitively through a fun recreational math puzzle, so you will always be able to recreate it for yourself and use it when you need it. (Also known as Square-And-Multiply and occasionally as the Chanda Sutra Method.) The video requires that you are familiar with binary.
Here's the tree I draw in the video: oeis.org/A232559
(In my video, there's a small error; I accidentally pruned out 27 and 29 and their descendants.)
You can learn about its history as part of the Chanda Sutra 8.28-31 at Wikipedia: en.wikipedia.o...

You made me understand in 6 minutes what my professor couldn't in an hour. Thank you.
This is excellent! Very nicely done. I will share this with plenty of students in the future.
another great Proof of Concept video!
get rid of the numbers from the nodes of that tree and it starts to look very familiar
Oh! What are you thinking of?
@@ProofofConceptMath that’s fibonacci’s tree from his original paper on those rabbits
@@debblez Oh, awesome, yes, it is!
damn you're right
