Section 1.1 Homework Hints
Problems 1-4
There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. For the most part, these questions do not have "right" or "wrong" answers. You should spend about five minutes in answering each of these questions.
Problems 5-6
Look at Pascal's triangle in Figure 1.4, and focus on the diagonals.
Problem 7
There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. Look at Example 2, and Figure 1.4. Do not worry about using any "correct" terminology in answering this question, but use your own words.
Problems 8-9
See Example 5
Problem 8a. Use the 5th row of Pascal's triangle. Remember the 5th row is the row whose second entry is 5.
Problem 8b . Use row 6.
Problem 9a . Use row 7.
Problem 9b . Use row 8.
Problems 10-13
See Examples 1 and 2; use Pascal's triangle. Draw the figure you are working with, and then either label the number of ways to get to each vertex (as in Example 1), or else count the number of rows and columns from A to B. For example, in Problem 11 , from A go up two rows and then over three rows. Start at the top of Pascal's triangle, and count down two and then over three to find the entry, which is the correct answer.
Problems 14-17
See Example 3 and number each vertex. Most of these locations have irregularities which prevents the efficient use of Pascal's triangle.
Problems 18-24
See Example 4 and look for a pattern.
For Problem 18 , if there is 1 penguin, there is 1 head and 2 feet. If there are 2 penguins, there are 2 heads and 4 feet. Write a table showing all possibilities to find the pattern.
For Problem 19 , be sure to read the first two sentences before you begin.
For Problem 20 , How much to ten (empty) crates weight?
For Problem 21 , draw a picture.
For Problems 22-23 , think about what you are reading before you answer.
Problems 25-26
Look at Pascal's triangle (Figure 1.4) and look for a pattern.
Problems 27-30
See Example 3 and number each vertex. Most of these locations have irregularities which prevents the efficient use of Pascal's triangle.
Problems 31-44
These are not typical math problems, but are problems that require only common sensE. See Examples 6 and 7 for some insight into the general problem-solving techniques need these problems.

    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.
