 ## 2. Variables
 
-Everything needs a name so we can refer to it. A variable, like in math, is just a name for a piece of data. In CFML, variables are very flexible and can be changed at any time. Variables are assigned using a single equals sign ( = ) where the **right** side of the equals sign is evaluated first, then the value is assigned to the variable named on the **left** side of the equals.

 ## 8. Structures
 
-A structure is a *collection of data* where each element of data is addressed by a name. As an analogy, think about a classroom of children. Under ideal circumstances, each student has a name and can be found by using that name. We might look in a science classroom for a child named Joey and that would result in finding an actual student. We could write this like "science["Joey"]" which could be read as "look in the collection named 'science' and find the thing named 'Joey'".

So to create a structure, the structures start with a curly bracket ```{```, have zero or more entries made up of a *key*, ```=```, and a *value* separated by commas, then end with a closing curly bracket ```}```. It is worth noting that when adding a key that is quoted, as is the case with "jill", the case sensitivity of the key will be preserved. Otherwise all keys will be uppercase.

 ## 9. Conditionals
 
-Conditional statements evaluate to "true" or "false" only. The most common conditional operators are ```==``` (equal), ```!=``` (not equal), ```>``` (greater than), ```>=``` (greater than or equal to), ```<``` (less than), and ```<=``` (less than or equal to). You can also define the operators as abbreviations: ```EQ```, ```NEQ```, ```GT```, ```GTE```, ```LT```, and ```LTE```. You can **only** use the abbreviations when using tags.
