2C: The Nature of Mathematics - Mathematical Inquiry**
**(grades 9-12, page 38)**
Some work in mathematics is much like a game mathematicians choose an interesting
set of rules and then play according to those rules to see what can happen.
The more interesting the results, the better. The only limit on the set
of rules is that they should not contradict one another. (1 of 2)

Appreciate the power of mathematical abstraction and symbolism
Much of the work of mathematicians involves a modeling cycle, which consists
of there steps: (1) using abstractions to represent things or ideas, (2)
manipulating the abstractions according to some logical rules, and (3)
checking how well the results match the original things or ideas. If the
match is not considered good enough, a new round of abstraction and manipulation
may begin. The actual thinking need not go through these processes in logical
order but may shift from one to another in any order. (2 of 2)
