comment The Association Bonus
Not that I think this is necessarily a realistic proposal, but it sounds like valuing the vote of someone with $p$ reputation points by an amount proportional to $\log(p)$ would allow more experienced individuals to have a bigger influence on the site's valuing of question and answer quality without drowning out the opinions of inexperienced users.

comment true/false linear questions
The only way to know if you are right or not is to come up with a justification for a true statement, or a counterexample for a false statement. For example, what is your justification that the answer to 1) is true? (The reason you are not asked to provide justification on your assignment/test is likely to save time, not because such justification is not needed to figure out the answer.)

comment How do you pronounce $\mathbb{R}^2, \dots, \mathbb{R}^n$
You can also call $\mathbb{R}^n$ "$n$-dimensional Euclidean space" if you want a phrase that sounds more noun-like.

comment Why do mathematicians sometimes assume famous conjectures in their research?
Unless you're in a logic class. Then , if there were no cell phones on, the students would answer the question about cell phones, "I don't know", "I don't know", ..., "I don't know", "Yes, all the cell phones are turned off." :)
