The SAT Mathematics section is divided into two parts: a calculator-allowed section and a no-calculator section. Understanding when and how to use your calculator effectively can significantly impact your score. This guide will help you master both sections with strategic approaches.
SAT Math Section Overview
No-Calculator Section
- • 20 questions
- • 25 minutes
- • Multiple choice and grid-in
- • Focus on mental math and estimation
Calculator Section
- • 38 questions
- • 55 minutes
- • Multiple choice and grid-in
- • Calculator allowed for complex calculations
No-Calculator Section Strategies
Mental Math Techniques
- Estimation: Round numbers to make calculations easier
- Factorization: Break down complex numbers into factors
- Pattern Recognition: Look for mathematical patterns and shortcuts
- Backsolving: Work backwards from answer choices
Common No-Calculator Topics
- Basic arithmetic operations
- Fractions and decimals
- Linear equations and inequalities
- Basic geometry and coordinate geometry
- Simple word problems
Calculator Section Strategies
When to Use Your Calculator
Calculator Use Cases:
- • Complex arithmetic calculations
- • Graphing functions and equations
- • Statistical calculations (mean, median, etc.)
- • Trigonometric functions
- • Time-consuming algebraic manipulations
Calculator Efficiency Tips
- Know Your Calculator: Practice with your specific calculator model
- Use Memory Functions: Store intermediate results

- Don't Over-rely: Use calculator only when necessary
Time Management Strategies
Time Allocation:
- • No-Calculator: ~1.25 minutes per question
- • Calculator: ~1.45 minutes per question
- • Skip difficult questions and return later
- • Use process of elimination for multiple choice
Practice Strategies
No-Calculator Practice
- Practice mental math daily
- Work on estimation skills
- Memorize common fractions and decimals
- Practice factoring and simplifying expressions
Calculator Practice
- Familiarize yourself with your calculator's functions
- Practice graphing equations
- Learn to use memory and storage features
- Practice complex calculations efficiently
Common Mistakes to Avoid
Avoid These Pitfalls:
- • Using calculator for simple mental math
- • Not checking calculator results
- • Spending too much time on complex calculations
- • Forgetting to bring a backup calculator
- • Not practicing with your specific calculator model
Conclusion
Mastering both calculator and no-calculator sections requires strategic practice and understanding when to use each approach. By following these strategies and dedicating time to practice, you can significantly improve your SAT Math score.
