ACT Mathematics Test Description
The ACT Mathematics Test is a 60-question, 60-minute test designed to measure the mathematical skills students have typically acquired in courses taken by the end of 11th grade.
The test presents multiple-choice questions that require you to use reasoning skills to solve practical problems in mathematics.
You need knowledge of basic formulas and computational skills to answer the problems, but you aren't required to know complex formulas and perform extensive computation.
You may use a calculator on the Mathematics Test. Visit http://actstudent.org/fag/answers/calculator.html for details about permitted and prohibited calculators. If you use a prohibited calculator, you will be dismissed and your answer document will not be scored. You are not required to use a calculator. All the problems can be solved without a calculator.
Content Covered by the ACT Mathematics Test
In the Mathematics Test, three subscores are based on six content areas: pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, and trigonometry.
· Pre-Algebra (23%). Questions in this content area are based on basic operations using whole numbers, decimals, fractions, and integers; place value; square roots and approximations; the concept of exponents; scientific notation; factors; ratio, proportion, and percent; linear equations in one variable; absolute value and ordering numbers by value; elementary counting techniques and simple probability; data collection, representation, and interpretation; and understanding simple descriptive statistics.
· Elementary Algebra (17%). Questions in this content area are based on properties of exponents and square roots, evaluation of algebraic expressions through substitution, using variables to express functional relationships, understanding algebraic operations, and the solution of quadratic equations by factoring.
Intermediate Algebra/Coordinate Geometry
· Intermediate Algebra (15%). Questions in this content area are based on an understanding of the quadratic formula, rational and radical expressions, absolute value equations and inequalities, sequences and patterns, systems of equations, quadratic inequalities, functions, modeling, matrices, roots of polynomials, and complex numbers.
· Coordinate Geometry (15%). Questions in this content area are based on graphing and the relations between equations and graphs, including points, lines, polynomials, circles, and other curves; graphing inequalities; slope; parallel and perpendicular lines; distance; midpoints; and conics.
