Quantitative Reasoning Fundamentals
Understanding the Quantitative Section
The Quantitative Reasoning section on the GMAT tests your problem-solving and data analysis skills. It covers arithmetic, algebra, geometry, and basic statistics.
Key Concepts
- Arithmetic (fractions, decimals, percentages)
- Algebra (equations, inequalities, word problems)
- Geometry (lines, angles, triangles, circles)
- Data interpretation (charts, graphs, tables)
Approaching Quantitative Questions
Focus on identifying what is being asked and eliminate unnecessary information. On the GMAT, mental math and estimation often save time.
Problem Solving vs. Data Sufficiency
The GMAT uses two question types:
- Problem Solving: Find the right answer from five choices.
- Data Sufficiency: Decide if the provided data is enough to answer the question.
Real-World Relevance
Quantitative skills help in everyday decision-making, like budgeting or analyzing trends in business.
Examples
Solving for \( x \) in the equation \( 2x + 3 = 11 \).
