Hum... I though the article was about something like the New Math[1] but... I actually learned math like that. (I'm from Portugal, and finished high-school around 10 years ago). Sincerely, I have no idea how the "old-fashioned way" works. I mean, venn diagrams and trees to add fractions. A variable change (!) to solve a quadratic equation. Those "new" methods were the methods I learned, and they were fast, efficient, and we add other algorithms to prove the validity of our answer.

Now I don't feel like I'm living in Bizarro World
