Instructions
Most of the exercise sets have an interactive part indicated by ¨, as in Exercises 3B¨. These questions have multiple choice answers. Click on your choice. If the answer is correct you will advance to the next question and eventually to the regular exercise set which has answers to all questions. If the answer is wrong, you will be transferred to a section which will explain the nature of the mistake and give you a second chance on a similar question. If the second question is answered correctly, you will end up at the regular exercise set. If the second answer is also incorrect, you will be transferred back to the examples that explain this type of problem.
