Questions may involve arithmetic operations, powers, operations on radical expressions, estimation, percent, absolute value, properties of integers (e.g., divisibility, factoring, prime numbers, odd and even integers), and the number line.

**Algebra**

Questions may involve rules of exponents, factoring and simplifying algebraic xpressions, understanding concepts of relations and functions, equations and inequalities, solving linear and quadratic equations and inequalities, solving simultaneous equations,

setting up equations to solve word problems, coordinate geometry, including slope, intercepts, and graphs of equations and inequalities, and applying basic algebra skills to solve problems.

**Geometry**

Questions may involve parallel lines, circles, triangles (including isosceles, equilateral, and 30°–60°–90° triangles), rectangles, other polygons, area, perimeter, volume, the Pythagorean Theorem, and angle measure in degrees. The ability to construct proofs is not measured.

**Data Analysis**

Questions may involve elementary probability, basic descriptive statistics (mean, median, mode, range, standard deviation, percentiles), and interpretation of data in graphs and tables (line graphs, bar graphs, circle graphs, frequency distributions).

**Math Symbols and Other Information**

The following information applies to all questions in the quantitative sections.

- Common math symbols may be used.
- Numbers: all numbers used are real numbers
- Figure:

– the positions of points, angles, regions, etc., can be assumed to be in the order shown;

angle measures are positive

– a line shown as straight can be assumed to be straight

– figures lie in a plane unless otherwise indicated

– do not assume figures are drawn to scale unless stated

It is important to familiarize yourself with the basic mathematical concepts in the GRE General Test. The publication *Math Review *is available for free download on the GRE Web site at **www.gre.org/****pracmats.html **and provides detailed information on the content of the quantitative section. The quantitative section contains the following question types:

• Quantitative Comparison Questions

• Problem Solving – Discrete Quantitative Questions

• Problem Solving – Data Interpretation Questions

Questions emphasize understanding basic principles and reasoning within the context of given information.
