GMAT Math: What you need to know Posted by ian on Fri 19 Sep 08 at 3:55pm GMAT Math: What do you need to know? The Quantitative section of the GMAT measures, according to GMAC, 'basic mathematical skills'. Even so, the test can still cover a wide range of mathematical topics. Most of the mathematics on the GMAT is material students learn in high school or before, with the possible exceptions of Number Theory and Counting and Probability. Below is a list of most of the topics you will need to know for the GMAT: BASIC ARITHMETIC AND PROPERTIES OF NUMBERS -Positive and Negative Numbers, and Zero -Integers -Fractions -Decimals -Arithmetic Operations (Addition, Subtraction, Multiplication, Division) -Exponents (including exponent rules) -Roots (including root rules) NUMBER THEORY -primes and prime factorizations -divisibility -least common multiples and greatest common divisors -remainders -even and odd numbers RATIOS AND PERCENTAGES -working with ratios -working with percentages, including percent increase and decrease STATISTICS -mean, median and mode -range and standard deviation -numbers in arithmetic progression ALGEBRA -single and multivariable linear equations -quadratic equations -other simple equations -inequalities -absolute value GEOMETRY -properties of triangles (Pythagorean Theorem, similar triangles, etc) -properties of quadrilaterals -properties of circles -basic angle relationships -area and perimeter -distances in three dimensions, and volumes of cylinders and rectangular prisms CO-ORDINATE GEOMETRY -distances between points -midpoints -areas -slopes -equations of lines -parallel and perpendicular lines -x and y intercepts -intersection point or points of two curves or lines COUNTING AND PROBABILITY -Venn diagrams -simple permutations and combinations -simple probability (including probability rules) WORD PROBLEMS -two equation/two unknown problems -rate problems -speed/distance/time problems -mixture problems -weighted averages -other word problems based on counting, least common multiples, percentages, etc. OTHER TOPICS -functions -sequences -data interpretation (reading charts, etc) ********************************* What You Do NOT Need to Know The GMAT is not a test of advanced mathematical knowledge. For example, you will not need to know: -Calculus (Derivatives, Integrals, Limits) -Logarithms -Trigonometry (Sines, Cosines, etc) among many other topics. |
