Algebra is the largest part of ACT Math, well over half the section when you combine pre-algebra, elementary algebra, and intermediate algebra. If you only had time to master one area, algebra would be the one to pick.
Pre-algebra basics
Fractions, decimals, percentages, ratios, proportions, averages, and number properties. These are usually the earlier, easier questions, fast points if your fundamentals are solid.
Elementary algebra
Linear equations and inequalities, exponents, and basic expressions. Expect to solve for variables, manipulate expressions, and work with simple functions.
Intermediate algebra
Quadratics, systems of equations, functions and their notation, sequences, and more complex inequalities. This is where many mid-level students lose points, and where a little targeted practice goes a long way.
Functions show up everywhere
Function notation, composition, and transformations appear throughout and among the hardest topics. Get comfortable reading what a function does, not just plugging in.
Memorize the core formulas
The quadratic formula, slope-intercept form, exponent rules, and factoring patterns are essential; see formulas to memorize for ACT Math. Instant recall frees you to focus on the problem.
Make algebra automatic
Because algebra dominates the section, fluency here lifts your whole score. Drill algebra-heavy sets on thirty-six and pair it with geometry from the full topic breakdown. For the overall plan, see how to improve your ACT Math score.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
