Ha ha. Everything you post is based off of YOUR assumptions... yet you come in here and say we're assuming this and that.
You're just ridiculous. Your ENTIRE argument in this is based on what YOU THINK was taught away from the math class.
So, it is totally coincidence that the teacher decided to name the slave Frederick? Really, that is your argument? If there was a Jewish girl named Anne Frank, would you pretend that a coincidential decision by a antisemetic teacher, or would you assume that maybe the kids were learning about Anne Frank?
Also, I am not accusing anybody of being racist. When you make an accusation about a math question (and in turn, a teacher) being racist, you should probably know the context.
