**Problem Solving**

When solving the homework problems to be turned in for a grade, please include the following steps:

1. **Read the question more than once**.
In fact, read it many times over until you are absolutely sure
what is being asked.

2. When appropriate, **draw a picture**
or pictures for what the question is asking.

3. Write down all the **known**
quantities with their symbols, values, and units.

4. List the unknown variables that **you
need to "find**" with their associated units. Be
sure you clearly understand what you need to solve for.

5. **Determine which equation(s) contain
the unknown variable** as a function of the knowns.

6. **Solve the equations** using
the known or assumed values, **being sure to carry along
the units. Show the intermediate steps.**

7. **Clearly identify your final answer **by
underlining it, or drawing a box around it.

8. **Check your answer**. Are the
units correct? Does it make sense?
