I remember when the common core debates were taking place, one of the memes running in parenting circles was a comparison of long division vs how common core taught division, and how much more “complicated” the common core version was.

But in reality the common core way explained the actual algorithm and the reason it worked so much better, and further, the only reason it appeared more complicated was because the people who were targeted by the meme already knew long division. If you took someone completely new to both methods, they’d find the more “complicated” algorithm far easier, because a large part of its complexity was explaining why the division worked, whereas long division was about memorizing a process.
