Really dig in her heels on the idea that 50% is not equal to 1/2. Thinking she must be joking I wrote a two-page proof explaining all of the reasons why 50% is equal to 1/2 and she was more than a little bit mad at me for not letting it go…
I ended up having to appeal to her department chair who walked into the room during my class, sat down at her computer, changed my grade on that test, and said to her, “I really shouldn’t have had to come down here to do this myself. I don’t want to have to come down here again. I’m asking you to drop it.”
She didn’t say another word for the rest of that class period and was not in school the next day. For the life of me I can’t understand what the fuck she was thinking was going to happen. Math doesn’t recognize opinions or authorities outside of math and she should have known that.
