SAT Math Objectives

You'll answer 58 math questions on the SAT. Your exam's algebra and functions questions form 35%-40% of the math test. Demonstrate your understanding of the following topics:

  • Solutions of linear equations and inequalities
  • Simplification and substitution in algebraic expressions
  • Exponent properties
  • Quadratic equations
  • Radical and rational equations
  • Equations of lines
  • Absolute value
  • Inverse and direct variation
  • Concepts of algebraic functions
  • Newly-defined symbols based on commonly used operations
  • Systems of inequalities and equations

These lessons allow you to study and practice working with inequalities in preparation for the SAT math. On the SAT, you'll earn one point for each correct answer. You won't lose any points for incorrect choices or for unanswered questions. Your scaled score will range from 200-800, with about a 500 indicating that you've scored around the national average.

What is an Inequality?

1. What is an Inequality?

Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!

Set Notation, Compound Inequalities, and Systems of Inequalities

2. Set Notation, Compound Inequalities, and Systems of Inequalities

In this lesson, we'll explore the conditions of compound inequalities and learn how to express them using set notation and interval notation. Test you knowledge afterward with a short quiz.

How to Graph 1- and 2-Variable Inequalities

3. How to Graph 1- and 2-Variable Inequalities

So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here!

How to Solve and Graph an Absolute Value Inequality

4. How to Solve and Graph an Absolute Value Inequality

Taking two skills and combining them to make a more complicated problem is a classic tactic in mathematics. If you feel confident with absolute values and inequalities, see if you can tackle them with their powers combined here!
