There are a few key abilities that form a foundation for doing math intuitively. The first is visualization. It is similar to using your imagination. If you have always been a 'visual' person, you will find some things easier. The first part of this chapter helps you develop this ability. If you already feel skilled in this area, this section can help you strengthen it in the specific ways that help you use it for math. Some people are naturally quite good at visualizing. If you feel that you don't really need training in this area, you can skip the first section. Just make sure you can do the exercises at the end of the chapter.
The last section introduces a tool called chunking. Chunking is a way to group (and un-group) symbols and expressions in particular ways that help us solve the equation.
