##### Strategy 23: understanding of the structure of expressions!

SAT Math questions fall into different categories called “domains.” One of these domains is Passport to Advanced Math: questions that ask you to analyze advanced mathematical expressions.

You will not need to know domain names for the test!
The SAT is designed to assess how ready you might be to tackle more advanced mathematics in college or later on in your career, so it includes some more advanced topics.

Passport to Advanced Math problems will test your understanding of the structure of expressions, and you will be asked to analyze, manipulate, and rewrite these expressions. This includes an understanding of the key parts of expressions, such as terms, factors, and coefficients.

This category also includes other skills crucial for success in later mathematics and scientific fields, for example
Solve quadratic and higher-order equations in one variable
Understand the graphs of quadratic and higher-order functions
Interpret a solution, constant variable, or term based on the context of a nonlinear equation in one variable
Create and use quadratic or exponential functions
Identifying exponential equations
