Understanding the HESI A2 Math Exam

The HESI A2 math exam assesses your foundational mathematical skills, crucial for success in various healthcare programs. The test covers a wide range of topics, including:

• Basic Arithmetic: This includes addition, subtraction, multiplication, and division of whole numbers, fractions, and decimals. You'll also need to understand order of operations (PEMDAS/BODMAS).

• Percentages and Ratios: Calculating percentages, converting percentages to decimals and fractions, and solving ratio and proportion problems are common.

• Fractions and Decimals: Converting between fractions and decimals, performing operations with fractions and decimals, and understanding concepts like least common denominator (LCD) are essential.

• Algebra: Basic algebraic concepts such as solving equations, inequalities, and working with exponents are often tested.

• Geometry: You might encounter problems related to basic geometric shapes, areas, perimeters, and volumes.

• Word Problems: A significant portion of the exam involves translating real-world scenarios into mathematical equations and solving them. These problems test your ability to apply your mathematical knowledge to practical situations.

Practice Problems: A Step-by-Step Approach

Let's tackle some practice problems, categorized by topic, to build your skills and confidence. Remember, understanding the process is just as important as getting the right answer.

1. Basic Arithmetic:

• Problem 1: Solve: 375 + 128 - 205 x 2 ÷ 5

  • Solution: Following the order of operations (PEMDAS/BODMAS), we first perform multiplication and division from left to right: 205 x 2 = 410; 410 ÷ 5 = 82. Then, we perform addition and subtraction from left to right: 375 + 128 = 503; 503 - 82 = 421. Therefore, the answer is 421.

• Problem 2: What is the result of 2/3 + 1/4 - 1/6?

  • Solution: To add and subtract fractions, we need a common denominator. The least common denominator (LCD) of 3, 4, and 6 is 12. Converting the fractions: (2/3) * (4/4) = 8/12; (1/4) * (3/3) = 3/12; (1/6) * (2/2) = 2/12. Now we can perform the operations: 8/12 + 3/12 - 2/12 = 9/12. Simplifying the fraction, we get 3/4.

• Problem 3: Calculate 0.75 x 3.2 + 1.5 ÷ 0.5

  • Solution: Following the order of operations: 0.75 x 3.2 = 2.4; 1.5 ÷ 0.5 = 3. Then, 2.4 + 3 = 5.4.

2. Percentages and Ratios:

• Problem 4: What is 15% of 600?

  • Solution: To find 15% of 600, we multiply 600 by 0.15 (15% as a decimal): 600 x 0.15 = 90.

• Problem 5: A recipe calls for 2 cups of flour and 1 cup of sugar. What is the ratio of flour to sugar?

  • Solution: The ratio of flour to sugar is 2:1.

• Problem 6: If 20% of a number is 30, what is the number?

  • Solution: Let the number be 'x'. We can write the equation: 0.20x = 30. Solving for x, we divide both sides by 0.20: x = 30 / 0.20 = 150.

3. Fractions and Decimals:

• Problem 7: Convert 3/8 to a decimal.

  • Solution: Divide the numerator (3) by the denominator (8): 3 ÷ 8 = 0.375.

• Problem 8: Convert 0.625 to a fraction in its simplest form.

  • Solution: 0.625 can be written as 625/1000. Simplifying the fraction by dividing both numerator and denominator by their greatest common divisor (125), we get 5/8.

4. Algebra:

• Problem 9: Solve for x: 2x + 5 = 11

  • Solution: Subtract 5 from both sides: 2x = 6. Divide both sides by 2: x = 3.

• Problem 10: Solve for y: 3y - 7 > 5

  • Solution: Add 7 to both sides: 3y > 12. Divide both sides by 3: y > 4.

5. Geometry:

• Problem 11: What is the area of a rectangle with a length of 8 cm and a width of 5 cm?

  • Solution: The area of a rectangle is calculated by multiplying length by width: 8 cm x 5 cm = 40 cm².

• Problem 12: What is the perimeter of a square with sides of 6 inches?

  • Solution: The perimeter of a square is 4 times the length of one side: 4 x 6 inches = 24 inches.

6. Word Problems:

• Problem 13: A nurse administers 250 ml of medication over 30 minutes. What is the rate of administration in ml per minute?

  • Solution: Divide the total volume by the total time: 250 ml / 30 minutes = 8.33 ml/minute (approximately).

• Problem 14: A doctor orders 500 mg of a medication. The available tablets contain 250 mg each. How many tablets should be administered?

  • Solution: Divide the required dosage by the dosage per tablet: 500 mg / 250 mg/tablet = 2 tablets.

Advanced Concepts and Strategies

Beyond the basics, the HESI A2 math exam may include more advanced concepts. Let's explore a few:

• Solving Systems of Equations: This involves finding the values of two or more variables that satisfy a set of equations simultaneously. Methods like substitution and elimination are commonly used.

• Working with Exponents and Roots: Understanding the rules of exponents (e.g., multiplying exponents with the same base) and how to simplify expressions with roots (square roots, cube roots) is crucial.

• Understanding Scientific Notation: This method is used to represent very large or very small numbers concisely. You'll need to be able to convert numbers to and from scientific notation and perform calculations with them.

Tips for Success

• Practice Regularly: Consistent practice is key. Work through numerous problems, focusing on areas where you feel less confident.

• Review Fundamental Concepts: Ensure a strong grasp of basic arithmetic, fractions, decimals, and percentages. These form the building blocks for more advanced topics.

• Understand the Question: Read each question carefully, identifying the key information and what is being asked.

• Show Your Work: Don't just write down the answer; show your steps. This helps you track your thought process and identify errors.

• Use Practice Exams: Take several practice exams under timed conditions to simulate the actual test environment. This will help manage your time effectively and reduce test anxiety.

• Identify Your Weaknesses: Pay particular attention to the areas where you struggle the most and dedicate extra time to improve your skills in those areas.

• Stay Calm and Focused: During the exam, remain calm and focused. Don't panic if you encounter a difficult problem; move on and return to it if time permits.

• Check Your Answers: If time allows, review your answers carefully before submitting the exam.
