What Math You Must Know to Do Well
By reading this to the end, you will know exactly what math topics show up on the ACT Math section, what you need to master to score higher, and how targeted practice can save you time and stress on test day. You will walk away with clarity instead of guessing and a simple plan for improvement.
The ACT Math section can feel overwhelming because it covers several years of math. The good news is this. The topics are predictable. Once you know what shows up, you can focus your study time where it actually matters.
Below are the main math topics you must know to do well on the ACT, explained in everyday language with examples.
1. Pre Algebra and Basic Number Skills
This is the foundation of the ACT Math section. These questions test how comfortable you are with numbers.
You should know
• Fractions, decimals, and percentages
• Ratios and proportions
• Positive and negative numbers
• Basic word problems
Example:
If a shirt costs 20 dollars and is discounted by 25 percent, how much do you pay?
You pay 15 dollars.
These problems are usually early in the test. Getting these right quickly builds confidence and saves time.
2. Algebra 1
Algebra makes up a big part of the ACT Math section. You must be comfortable solving for x.
You should know
• Solving one step and multi step equations
• Working with inequalities
• Substituting values into formulas
• Simple systems of equations
Example:
Solve 2x + 6 = 14
Subtract 6 from both sides and divide by 2.
x = 4
Many students lose points here because of small mistakes. This is one of the easiest areas to improve with guided practice.
3. Algebra 2
This is where the questions start to feel harder, but they are still very learnable.
You should know
• Quadratic equations
• Factoring
• Exponents and radicals
• Functions and graph interpretation
Example:
Factor x² − 5x + 6
The answer is (x − 2)(x − 3)
You do not need to be perfect. You just need to recognize patterns and know a few key strategies.
4. Geometry
Geometry is another major part of the ACT Math section.
You should know
• Area and perimeter
• Volume of 3D shapes
• Angles and triangles
• Circles and basic coordinate geometry
Example:
What is the area of a rectangle with length 8 and width 5?
Area = 40
Formulas are provided on the test, but knowing when and how to use them is the real skill.
5. Trigonometry
This is usually a smaller portion, but it can make the difference between an average score and a strong score.
You should know
• Sine, cosine, and tangent
• Right triangle relationships
• Basic angle concepts
Example:
If sin θ = opposite over hypotenuse, and the opposite side is 3 while the hypotenuse is 5, then sin θ = 3/5.
You do not need advanced trig. Just the basics and how to apply them.
6. Word Problems and Data Interpretation
These questions test how well you read and understand math in real life situations.
You should know
• Translating words into equations
• Reading charts and graphs
• Averages and probability
Example:
If the average of 4 numbers is 10, their total is 40.
Many students rush here. Slowing down and setting up the problem correctly makes a huge difference.
