3. One of the most efficient ways to memorize the important formulas for GMAT is by using formula flashcards. These handy tools allow you to review key formulas on the go and ensure you retain essential information. Flashcards help in active recall, which is proven to improve memory retention. By organizing formulas into categories such as arithmetic, algebra, and geometry, you can focus on one area at a time and build your confidence progressively. Example Flashcard Setup: Front: What is the formula for the area of a circle? Back: Area = π * r² Front: What is the quadratic formula? Back: x = (-b ± √(b² - 4ac)) / 2a Creating your own GMAT formula flashcards or using pre-made ones allows you to personalize your learning. You can add tips or notes on the back of each card to remind yourself of tricky concepts or shortcuts. For instance, on a flashcard about percentage increase, you can note that "increase" means adding the percentage to 100% before calculating. Incorporating daily review sessions with these flashcards will help reinforce the important formulas for GMAT, making it easier to retrieve them quickly during the GMAT exam. Core Arithmetic Formulas Arithmetic is one of the most fundamental areas tested in the GMAT quantitative section. Mastering the important formulas for GMAT in arithmetic will give you an edge in solving problems related to properties of numbers, percentages, ratios, averages, and interest calculations. Below are the essential arithmetic formulas you should know: Topic Formula Example Properties of Integers Even + Even = Even, Odd × Odd = Odd 2 + 2 = 4, 3 × 3 = 9 Percentage ( Part / Whole ) × 100 ( 50 / 200 ) × 100 = 25% Ratio Formula a : b = a / b 3:1 = 3 / 1 Average Sum of terms / No. of terms (50 + 60 + 70) / 3 = 60 3/11

4. Properties of Integers Understanding integers is crucial for many GMAT problems. Key properties include: Even + Even = Even Odd + Odd = Even Even × Even = Even Odd × Odd = Odd These simple properties are often tested in number properties questions. Percentages Percentages are commonly used to measure change, profit, or discounts. Here are two essential formulas: Percentage Formula: (Part/Whole) × 100 Percentage Increase/Decrease: ((New Value – Old Value) / Old Value) × 100 Want to know how we can increase your Admission Chances by 300%?

Schedule an Appointment Ratios and Proportions Ratios compare two quantities, while proportions indicate that two ratios are equal. Ratio Formula: a = a/b Proportion Formula: a/b = c/d These are essential when solving problems involving comparison of quantities or scaling. Averages and Weighted Averages The formula for an average is straightforward but frequently tested: Average: Sum of terms / Number of terms For weighted averages, the formula adjusts based on the weight (importance) of each term: Weighted Average: (w1 × x1 + w2 × x2 + ... + wn × xn) / (w1 + w2 + ... + wn) 4/11

5. Interest Calculations Interest problems usually involve simple or compound interest: Simple Interest Formula: I = P×R×T, where P is principal, R is the rate, and T is time. Compound Interest Formula: A= P × (1 + R/N )nt , where A is the amount, P is the principal, R is the rate, n is the number of times the interest is compounded per year, and T is time in years. Key Algebra Formulas Algebra plays a significant role in the GMAT quantitative section, and knowing the important formulas for GMAT algebra is essential to solving complex equations efficiently. Whether it's linear equations, quadratic equations, or inequalities, these formulas form the foundation of many GMAT problems. Linear Equations Linear equations describe a straight-line relationship between two variables. The standard form is: 5/11

6. Formula: y = mx+b, where m is the slope and b is the y-intercept. Linear equations can also be written in the form ax+by=c, which is often used in simultaneous equations or when finding points of intersection. Want to learn how Adcoms evaluate your profile?

Evaluate Me Quadratic Equations Quadratic equations involve terms raised to the power of two and follow the general form: Formula: ax2+bx+c=0 To solve quadratic equations, you can use the quadratic formula. Inequalities Inequalities are similar to equations but involve greater than (>) or less than (<) relationships. The key property of inequalities is that multiplying or dividing both sides by a negative number reverses the inequality sign. Example: If 3x>6, dividing both sides by 3 gives x > 2. Important Tip: If you divide or multiply by a negative number, reverse the inequality sign. Functions and Graphs Functions describe relationships where each input has a single output. The most common form of a function is: Formula: f(x)=ax+b, where x is the input and f(x) is the output. Graphing functions helps you visualize their behavior. For instance, linear functions create straight lines, while quadratic functions create parabolas. Essential Geometry Formulas 6/11

7. Geometry is a key component of the GMAT quantitative section, and knowing the important formulas for GMAT geometry will help you solve problems related to shapes, areas, and distances. Below are the essential geometry formulas you need to memorize: Shape Perimeter Formula Area Formula Rectangle 2(l + w) l × w Circle 2πr πr² Triangle Sum of all sides (1/2) × base × height Perimeter and Area of Basic Shapes Understanding the perimeter and area of basic geometric shapes is vital for solving a variety of questions: Rectangle Perimeter: 2(l+w), where l is the length and w is the width. Area: l×w Circle Perimeter (Circumference): 2πr, where r is the radius. Area: πr2 Confused about which Schools to Target? 7/11

8. Browse through our list of Top B-Schools Explore Schools Triangle Perimeter: Sum of all sides. Area: 1/2×base×height Properties of Triangles Triangles are one of the most frequently tested shapes on the GMAT. Key properties include: Sum of Angles: The sum of the interior angles of any triangle is always 180°. Isosceles Triangle: Two sides are equal in length, and the two base angles are equal. Equilateral Triangle: All three sides are equal, and each angle is 60°. Area of Right-Angle Triangle: 1/2×base×height Pythagorean Theorem The Pythagorean theorem is crucial for solving problems related to right-angle triangles. It relates the lengths of the sides of a right triangle: Formula: a2+b2=c2, where a and b are the lengths of the legs, and c is the length of the hypotenuse. This formula is particularly useful when calculating distances or verifying whether a triangle is a right-angle triangle. 8/11

While the GMAT tests your reasoning skills, knowing key formulas by heart will allow you to focus more on problem-solving rather than spending time deriving formulas during the exam. However, not all formulas carry the same weight, so it’s important to prioritize which ones to memorize. Helpful Tips for Memorizing Formulas: Start with the Basics: Focus on core arithmetic, algebra, and geometry formulas that are used frequently. These include percentages, ratios, linear and quadratic equations, and the area and perimeter of shapes. Understand the Concepts: Simply memorizing formulas isn’t enough. Understand when and how to apply each formula. For example, knowing that the quadratic formula solves any second-degree equation will help you quickly identify when to use it. Use Flashcards: As mentioned earlier, flashcards are a great way to regularly review formulas. Write the formula on one side and an example problem or a note about its use on the other. Focus on High-Yield Areas: Some topics, like number properties, geometry, and algebra, are tested more frequently than others. Prioritize learning formulas from these areas first. Practice Regularly: Apply the formulas you’ve memorized by solving practice questions. The more you use them, the easier it becomes to recall them under exam conditions. 9/11
