WhiskeyJuvenile posted:The "Johnny got this wrong answer.What mistake did he make?" questions are probably the best "do you understand arithmetic" questions I've ever seen As a teacher, I don't think we spend nearly enough time training students how to identify errors and develop intuitive rules of thumb around material. The step before "Is this correct?" should be "Is this answer not batshit crazy?"

Basically this: http://www.smbc-comics.com/index.php?db=comics&id=1995 I always found the Incompleteness Theorems to be a comfort against math anxiety. Worried about making a mistake? It's all bullshit anyway; the answer is based on assumptions. Change the assumptions and you change the answer. Not only that, but we CAN'T come up with something that works all the time. It's provably impossible. Make sure your reasoning is sound and everything should work out. I wish we had focused more on process and playing with math in High School. Before college I learned how to do computation; in college I learned how to do MATH.
