We've written individual informational and strategy guides for every ACT Math topic, and provide practice problems with answer explanations for each.
Strategies for Multiple Types of ACT Math Problems
Many ACT Math problems can be solved in multiple ways, and two strategies in particular can help you solve several kinds of questions. These key strategies give you the power to answer questions on math topics you aren't sure how to solve using the "traditional" way, and help you double-check that you've chosen the correct answer.
Instead of solving math problems directly, you can use the structure of the test against itself. These two essential strategies involve putting answer choices back into problems and using numbers to test equations and inequalities. They're especially helpful for complex algebra problems—nothing beats working with real numbers instead of variables!
Now, let's look at each math topic on the ACT by subject.
