# Homework Hints 1-1

[tippy title=”Problems 1-6″] Problems 1-6
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.[/tippy]

[tippy title=”Problems 7-8″]Problems 7-8
Look at Pascal’s triangle in Figure 1.4, and focus on the diagonals.[/tippy]

[tippy title=”Problems 9-10″] Problems 9-10
See Example 5
Problem 9a. Use the 5th row of Pascal’s triangle. Remember the 5th row is the row whose second entry is 5.
Problem 9b. Use row 6.
Problem 10a. Use row 7.
Problem 10b. Use row 8.[/tippy]

[tippy title=”Problems 11-14″] Problems 11-14
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 12, 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.[/tippy]

[tippy title=”Problems 15-18″] Problems 15-18
See Example 3 and number each vertex. Most of these locations have irregularities which prevents the efficient use of Pascal’s triangle. [/tippy]

[tippy title=”Problem 19″]Problem 19
See the traffic directors function as points in Pascal’s triangle. [/tippy]

[tippy title=”Problem 20″]Problem 20
This problem is an extension of Problem 19. [/tippy]

[tippy title=”Problem 21″]
For Problem 21, how much do ten (empty) crates weigh? [/tippy]

[tippy title=”Problem 22″]
For Problem 22, draw a picture. [/tippy]

[tippy title=”Problems 23-24″]

[tippy title=”Problems 25-26″]
Problems 25-26
Look at Pascal’s triangle (Figure 1.4) and look for a pattern. [/tippy]

[tippy title=”Problems 27-30″] 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. [/tippy]

[tippy title=”Problems 31-44″] 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.[/tippy]

### 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.
