What are the math skills that you need to know?

Arithmetic

• properties and types of integers, such as divisibility, factorization, prime numbers, remainders and odd and even integers
• arithmetic operations, exponents and radicals
• concepts such as estimation, percent, ratio, rate, absolute value, the number line, decimal representation and sequences of numbers.

Algebra

• operations with exponents
• factoring and simplifying algebraic expressions
• relations, functions, equations and inequalities
• solving linear and quadratic equations and inequalities
• solving simultaneous equations and inequalities
• setting up equations to solve word problems
• coordinate geometry, including slopes and intercepts of lines and graphs of functions, equations and inequalities.

Geometry

• parallel and perpendicular lines, circles, triangles — including isosceles, equilateral and 30°-60°-90° triangles — quadrilaterals, other polygons, congruent and similar figures
• three-dimensional figures, area, perimeter, volume
• the Pythagorean theorem
• angle measurement in degrees.
• NOTE: The ability to construct proofs is not tested.

Data analysis

• basic descriptive statistics, such as mean, median, mode, range, standard deviation, interquartile range, quartiles and percentiles
• interpretation of data in tables and graphs, such as line graphs, bar graphs, circle graphs, boxplots, scatterplots and frequency distributions
• elementary probability, such as probabilities of compound events and independent events; random variables and probability distributions, including normal distributions; and counting methods, such as combinations, permutations and Venn diagrams
• NOTE: These topics are typically taught in high school algebra courses or introductory statistics courses. Inferential statistics is not tested.
