Let me explain how multiplication tables are often taught wrong, and show a bunch of underrated patterns within them:
0:00 - Part 1: Metamemorization
2:26 - Parts 2 and 3: Primes and Composites
5:58 - Parts 4, 8, and 9: Squares and Almost-Squares
13:30 - Parts 10 and 100 and etc: The Beauty of Zooming Out
19:40 - Part Infinity: Conclusionfinity
Thanks for watching! Leave a comment about your favorite part. And consider showing this video to a teacher in your life (if teachers incorporated more of these patterns when teaching arithmetic, I don’t think as many people would hate multiplication tables!).
If you want bonus content, I've been doing livestreams every few days on my @Domotro channel, which are saved like videos on that channel's "live" tab afterwards.
This episode was directed/edited/soundtracked by me (Domotro) and was filmed by Carlo Trappenberg, with some additional filming help from Raphael Matos and Andy Sykora.

In case anybody searches any of these terms, some topics mentioned in this episode include: times tables / multiplication tables, memorization vs. learning patterns, square numbers, almost-square numbers such as pronic numbers and numbers of the form n^2 - 1, graphs such as y=n/x, number factors, where numbers of different amounts of digits live on the times table, number theory, random fun math facts, a few arithmetic tricks, feeding some squirrels, and more!
Disclaimer: Do NOT copy any dangerous-seeming actions (which were actually performed in a careful way) involving fire, tools, or other chaotic activities you may see in Combo Class episodes. This is an episode of a show that is purely meant to provide entertainment and education. Also, do not copy the squirrel-feeding without doing research, since if you feed wild squirrels in certain habitats, it will actually be bad for their diet and hunting skills in the long term.
