GMAT Score Report Deciphered: Understand the Four Major Quantitative Topic Categories in Seconds
What specific math concepts do these specialized terms (e.g., Rates/Ratio/Percent, Value/Order/Factors) actually represent?
I believe this is a common question for many test-takers. This time, Dustin has compiled the official definitions for you, along with simple example questions and a GMAT Club topic classification cross-reference table, so you can go from analysis to practice, all in one go.
1. Rates/Ratio/Percent
| Chinese | Example Question |
| Conversions – Conversions between fractions/decimals/percents | Convert 0.75 to a percentage. |
| Graduated Rates – Such as taxi fares and related pricing models | Calculate the total cost for 10 kilometers if the base fare is 5 units and the charge is 2 units per kilometer. |
| Basic Percents – Basic percentage problems | What is 5% of 8? |
| Ratios, Proportions – With numerical or algebraic ratios as the main focus | If 3:4 = x:16, find the value of x. |
2. Value/Order/Factors
| Chinese | Example Question |
| Absolute Value – Focus on the application and properties of the absolute value function | Find |
| Decimal Calculations – Addition, subtraction, multiplication, and division of numbers in decimal form | Calculate the result of 0.6 x 0.4. |
| Exponents – Understanding the meaning and properties of exponents | Calculate the value of 2^3. |
| Factors, Multiples, Divisibility – Study the divisibility properties of positive integers | List all factors of 12. |
| Number Line and Order – Application of number line and order properties | Compare -3 and 2 on a number line. Which number is greater? |
| Place Value – Understanding the place value of decimal numbers | In the number 532, what is the digit in the tens place? |
| Positive and Negative Numbers – Maintaining or not maintaining positive and negative signs in addition, subtraction, multiplication, division, and exponentiation | Calculate the result of -7 + 4. |
| Remainders – Exploring the application of remainders in division operations | Divide 20 by 6 and find the remainder. |
3. Equalities/Inequalities/Algebra
| Chinese | Example Question |
| Algebraic Manipulation – Rearranging algebraic expressions | Simplify the expression 3(x + 2) – x. |
| Applying Formulas – Applying specific formulas | If the radius of a circle is 3, find its circumference. |
| Linear Equations – Solving linear equations | Solve the equation 2x + 3 = 7. |
| Linear Inequalities – Solving linear inequalities | Solve the inequality 3x – 5 < 10. |
| Unit Conversions – Unit conversions for length, area, volume, etc. | Convert 5 meters to centimeters. |
| New Defined Functions – Using new functions defined in the problem | If the function f(x) = 2x + 1 is defined, find f(3). |
| Quadratic/Other Equations/Inequalities – Solving equations or inequalities of degree higher than one | Solve the equation x^2 – 4 = 0. |
| Systems of Equations/Inequalities – Solving a set of equations or inequalities | Solve the system of equations x + y = 10 and x – y = 2. |
| Translating to Algebraic Expressions – Converting word descriptions into mathematical expressions | Convert “twice a number plus 3” into an algebraic expression. |
4. Counting/Sets/Series
| Chinese | Example Question |
| Counting (Combinatorics) – Basic combinatorial concepts, such as permutations and combinations | How many ways are there to choose 2 people from a group of 5? |
| Estimation – Numerical estimation | Estimate the value of 52 x 19. |
| Series and Sequences – Study of sequences or sums of sequences | Find the sum of the first four terms of the sequence 2, 4, 6, 8. |
| Sets – Understanding basic set concepts, such as union and intersection | Given A = {1, 2, 3} and B = {3, 4, 5}, find the intersection of A and B. |
