Note: Homework Hints are given only for the Level 1 and Level 2 problems.
However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
There are many sources for homework help on the internet.

You do not need to understand anything about circuits or electricity to be able to answer these questions.
These problems ask about the basic notation the symbols used when drawing circuits. You should be able to work all of these problems even if they are not assigned. You do not need to understand anything about circuits or electricity to be able to answer these questions.
These problems ask about basic circuit diagrams.
If you do not recognize the circuit, then begin with a truth table, and then compare with Table 3.5 or Table 3.9.
These problems ask about basic gate diagrams.
See Example 2.
See Example 2; notice that these all involve implication, so you may need to review Table 3.6.
See Examples 2 and 3.
The difference between these problems and Example 2, is there are three propositions, so the truth tables will have eight entries.
