The most difficult part of the material for me was the new vocabulary and also the truth tables. There were a lot of writing examples which was new for a math course. At first the truth table didn't make sense because I was looking at the example which had 4 truths, whereas the table only showed one. Then I realized that the table was not depicting a ratio, but just that the answer is either true or false.
The reading about the implication in section 2.4 reminded me of the form of a hypothesis if...then that I have used in science course like chemistry. I wonder if I do use the mathematical expression in a lab report, it may be informal rather than writing it out. The story reminded me of another course, where the professor will give us an A if we get an A on the final. He called it the repentance method.
