Mathematics
ACT Math Section
The ACT math section is 45 questions in 50 minutes — just over a minute each. It tests number and quantity, algebra, functions, geometry, and statistics and probability, including some trigonometry. Pacing is the hard part: fast accurate test-taking matters as much as content mastery.
How to Approach ACT Math Section
Cover the content areas
Number and quantity, algebra, functions, geometry, and statistics and probability — plus questions that combine skills and model real situations. Geometry, including some trigonometry, carries more weight than on the SAT.
Master pacing
45 questions in 50 minutes is about 67 seconds each. Easier questions early on should take well under a minute — bank that time for the harder ones at the end. Skip and return if stuck more than 90 seconds.
Strategy: plug in numbers
When a question has variables in the answer choices, pick simple numbers (avoid 0, 1, and numbers in the problem), plug into the original, then test each answer choice. Often faster than algebra.
Frequently Asked Questions
How is ACT math different from SAT math?+
ACT math has more geometry and trigonometry and is faster-paced. SAT math leans harder on algebra and is adaptive — your first module sets the difficulty of the second. Both now allow a calculator on every math question.
What calculator should I use?+
Any approved scientific or graphing calculator. TI-84 is the most common for graphing. The ACT doesn't require a graphing calculator — a scientific calculator is enough — but knowing your tool well matters more than which tool.
What's a good ACT math score?+
ACT subscores are 1-36. 30+ is competitive for most colleges; 33+ for top-tier. The national average is about 19. The math section often determines whether someone clears a school's middle-50% range.
