**Benchmark
2A: The Nature of Mathematics - Patterns and Relationships**
**(grades 9-12, page 29)**
Mathematics is the study of patterns or relationships, whereas natural
science is concerned only with those patterns that are relevant to the
observable world. Although mathematics began long ago in practical problems,
it soon focused on abstractions from the material world, and then on even
more abstract relationships among those abstractions. (1 of 4)

Use and value the connections between mathematics and other disciplines

As in other sciences, simplicity is one of the highest values in mathematics.
Some mathematicians try to identify the smallest set of rules from which
many other propositions can be logically derived. (2 of 4)

Appreciate the economy, power, and elegance of mathematical notation
and its role in the development of mathematical ideas
Theories and applications in mathematical work influence each other. Sometimes
a practical problem leads to the development of new mathematical theories;
often mathematics developed for its own sake turns out to have practical
applications. (3 of 4)
