Content Standards Interpret complicated expressions by viewing one

or more of their parts as a single entity. Use the structure of an expression to identify

ways to rewrite it.

Mathematical Practices Look for and make use of structure.

Objectives Evaluate numerical expressions by using

the order of operations.
