Solving problems in your life

Now is the time to advance your strategies for scheduling next semester’s classes. Show how the
structure of the data sets, scheduling, and the use of set theory helps you to optimize how you will
lay out your schedule.

Reflecting on and appreciating your learning
1. Very complex problems can usually be broken down into a collection of smaller problems. Each of
the smaller problems can then be solved by applying mathematical knowledge. How do you filter the
complex content in order to see and solve the smaller problems that comprise it?
2. As you move through mathematics, encountering (and learning) increasingly complex ideas and
operations, how do you characterize each new mathematical object that you learn to use?
3. What is the relationship between “union and intersection” and “convergent and divergent thinking”?
