Putting the Big Four Operations to Work
In This Chapter
Identifying which operations are inverses of each other
Knowing the operations that are commutative, associative, and distributive
Performing the Big Four operations on negative numbers
Using four symbols for inequality
Understanding exponents, roots, and absolute values
When you understand the Big Four operations that I cover in Chapter 3 — adding, subtracting, multiplying, and dividing — you can begin to look at math on a whole new level. In this chapter, you extend your understanding of the Big Four operations and move beyond them. I begin by focusing on four important properties of the Big Four operations: inverse operations, commutative operations, associative operations, and distribution. Then I show you how to perform the Big Four on negative numbers.
I continue by introducing you to some important symbols for inequality. Finally, you're ready to move beyond the Big Four by discovering three more advanced operations: ...
