explain the ways.

Part 4 – Reflection

This question required:

1. The course resources and your teacher says that note taking is really helpful in mathematics. As you

went through this course would you agree or disagree with that? What additional advice would you give

to a student that is beginning the course today?

Choose 2 of the following questions:

2. Briefly explain a concept in this module and give at least one real world example that demonstrates the
