Ive always hated math so much
It's like numbers are taunting me.
So I'm going to post this Euclid algorithm page from Penrose "Emperor's New Mind" pretending to understand it.
His example ends in "21"
Discussion
I had to tell myself stories about numbers to make them make sense.
1 and 3 were two boys in class that both liked 4.
2 and 4 were two girls that both liked 6.
2 didn't like 7 (annoying boy) but they would hang out if 9 was around.
3 and 5 both had a crush on 8 but she was in the next grade.
Etc
Math is usually not taught very well. Its hard to teach...
