The homework will be graded on both completeness and accuracy. Please write all the steps necessary to understand the line of arguments you used to get your answer.  Remember, part of this class is to be able to write "Valid arguments" for justifying your answers. So please write down the steps for each answer. Having said that, some questions do not need an argument; e.g., Exercise 1.9.4 just needs the answers.
