1. (4 pts) The name of this course is "Introduction to Computer Science". Yet, the authors of our textbook, in Chapter 1, indicate that there is some difficulty with applying the word "science" to Computer Science. They make the point that Computer Science is fundamentally different from Biology, Chemistry or Physics. Why do the authors make this claim—that is, what is different about Computer Science vs. those other fields?
   
   
   
   
   
2. (4 pts) The authors state that Computer Science is the study of Algorithms. According to the authors, what is an algorithm?
   
   
   
   
   
3. On p. 11, there is an example of a Python session. There are several symbols in this session. Describe what each of these symbols means:

4. Read pages 10-17 about the three types of numbers that we can work with in the Python programming language. These include integers, floating-point, and complex numbers.
   
   
   
   
   1. (4 pts) Which of these types of number would we use to represent your GPA?
      
      Circle one:       integer               floating-pt               complex
      
      
      
   2. (4 pts) Which of these types of numbers would we use to represent the number of students registered for this class?
      
      Circle one:       integer               floating-pt               complex
      
      
      
   3. (4 pts) Which of these types of numbers would we use to represent the square root of -4 ?
      
      Circle one:       integer               floating-pt               complex
      
      
      
   4. (4 pts) Fill in the blank: A complex number has an imaginary part and a _________________ part.
      
      
      
   5. (4 pts) In Math class, we often use the letter i to represent the square root of negative 1, and we write complex numbers in the format (a + bi).
      
      What letter of the alphabet is used in Python to represent the imaginary part of a complex number?
