Next, make sure you understand the types of problems in Chapter 3.
TYPES OF PROBLEMS
Determine whether a sentence is a statement. [3.1]
Find truth value of simple and compound statements. [3.1]
Write the negation of all, some, and not. [3.1]
Translate statements into symbolic form. [3.1-3.3]
Translate symbolic form into verbal statements. [3.2, 3.3]
Construct a truth table for a given symbolic form. [3.2]
Apply the definition of the conditional. [3.2]
Write the converse, inverse, and contrapositive for a given statement. [3.2]
Determine whether a given symbolic statement is true or false. [3.2]
Decide whether a given statement is a tautology. [3.3]
Write an implication as a disjunction. [3.3]

Prove logical statements. [3.3, 3.4]
Determine whether a given argument is valid or invalid. [3.4]
Classify valid forms of reasoning and recognize common fallacies. [3.4]
Find a valid conclusion for a given argument. [3.4]
Classify items as an undefined term, defined term, postulate, or theorem. [3.5]
Prove simple theorems using given definitions and postulates. [3.5]
Solve logical puzzles. [3.5]

Once again, see if you can verbalize (to yourself) how to do each of the listed types of problems. Work all of Chapter 3 Review Questions (whether they are assigned or not).
Work through all of the problems before looking at the answers, and then correct each of the problems. The entire solution is shown in the answer section at the back of the text. If you worked the problem correctly, move on to the next problem, but if you did not work it correctly (or you did not know what to do), look back in the chapter to study the procedure, or ask your instructor.
Finally, go back over the homework problems you have been assigned. If you worked a problem correctly, move on the next problem, but if you
missed it on your homework, then you should look back in the text or talk to your instructor about how to work the problem. If you follow these steps, you should be successful with your review of this chapter.
We give all of the answers to the Chapter Review questions (not just the odd-numbered questions), so be sure to check your work with the answers as you prepare for an examination.
