A Guide to the GRE/Math
Introduction to GRE MathEdit
The GRE tests only basic math universal to high school curricula. The exam generally does not test any math beyond high school geometry; there is no trigonometry or calculus on the test. Its math can be broken into essentially four categories.
The GRE frequently tests knowledge of these mathematical concepts such as the rules of radicals, exponents, absolute value, positives, negatives, and inverses.
Algebra refers to the use of variables and equations to solve problems, such as by substituting a letter-value for an unknown. The GRE heavily tests algebra, particularly in problems involving rates or proportions.
Geometry refers to the variety of rules used to calculate attributes of lines and shapes. The GRE tests a great deal of geometry, especially triangles, squares and circles.
Every GRE math section has a section of questions based on a chart, designed to test data interpretation skills. Many of the other questions test statistical concepts such as averages and standard deviation.
