Master The Arithmetic Reasoning On ASVAB
Understand the Structure of the Test
The Arithmetic Reasoning section consists of word problems that require basic arithmetic skills. You’ll be dealing with:
- Simple arithmetic operations such as addition, subtraction, multiplication, division.
- Working with fractions, decimals, and percentages
- Applying basic algebraic concepts
Knowing this upfront helps you prepare with focus. Be aware that these problems are typically framed in a real-world context, so it’s not just about numbers, but also reading comprehension.
Word problems can be overwhelming, but breaking them down into smaller, more manageable pieces helps a lot.
Use Elimination on Multiple-Choice Questions
When faced with multiple-choice options, the process of elimination is a powerful tool,
Apply Mental Math Tricks
Mental math is a huge time-saver, especially when you don’t have a calculator. Here are some tips:
- Multiplying by 9: To multiply by 9, multiply by 10 and then subtract the original number. For example, 9 × 6 = (6 × 10) - 6 = 60 - 6 = 54.
- Dividing by 5: To divide by 5, multiply by 2 and then divide by 10. For example, 20 ÷ 5 = (20 × 2) ÷ 10 = 40 ÷ 10 = 4.
- Handling percentages: To find 10% of a number, just move the decimal place one position to the left. To find 20%, double the 10%.
Since ASVAB Arithmetic Reasoning problems are set in real-world scenarios (e.g., distance, time, work, and money), it’s helpful to practice problems that mirror everyday situations:
- Time, Distance, and Rate: "If a car travels 60 miles per hour, how long will it take to travel 180 miles?"
- Work Problems: "If 3 workers can complete a job in 6 hours, how long would it take 6 workers to do the same job?"
- Percentages: "What is 25% of 80?"
While the ASVAB doesn’t allow you to bring notes, memorizing a few key formulas can make a huge difference:
- Distance = Rate × Time: Common in problems involving travel.
- Work = Rate × Time: Useful for calculating how long a task will take with multiple people working together.
- Percentage = (Part/Whole) × 100: Helpful for questions about percentages or finding the percent increase/decrease.
If you come across a tough question, don’t dwell on it. Use the skip and return method,
- Quickly skip the question and move on to others you can answer confidently.
- When you’ve completed easier questions, return to the difficult ones with a fresh perspective.
You have 39 questions to answer in 30 minutes, which gives you about 45 seconds per question.
Use Logical Reasoning
If you don’t know the exact math for a question, rely on logical reasoning. Think about the problem and possible outcomes:
- If the problem involves increasing or decreasing a quantity, ask yourself whether the answer will be higher or lower than the starting value.
- Check if the answer choices seem reasonable based on the context of the problem.
Finally, don’t let stress get to you! A calm and confident mindset can make a huge difference in your performance. Believe in your preparation, trust your instincts, and stay focused.
Keep practicing and refining these strategies, and you'll boost your score in no time!
