Mastering ASVAB Mathematics Knowledge
The Mathematics Knowledge subtest evaluates your understanding of core high school mathematical principles. Let’s examine some sample questions to illustrate the question types:
1. Mathematics Knowledge Sample Question:
For all x, (x – 4)(x + 4) = ?
A. x2 + 2x – 16
B. x2 – 2x + 16
C. x2 + 16
D. x2 – 16
E. ±4
Answer:
The correct answer is D.
Explanation: This question tests your knowledge of algebraic identities. The expression (x – 4)(x + 4) is a classic example of the difference of squares formula: a² – b² = (a + b)(a – b). Applying this formula, we directly get (x – 4)(x + 4) = x² – 4² = x² – 16.
Alternatively, if you don’t recall the formula, you can expand the expression by multiplying each term: (x – 4)(x + 4) = x² + 4x – 4x – 16 = x² – 16.
2. Mathematics Knowledge Sample Question:
7.4 × 10² decimeters equal:
A. 74 centimeters
B. 740 centimeters
C. 7,400 centimeters
D. 74,000 centimeters
E. 740,000 centimeters
Answer:
The correct answer is C. 7,400 centimeters.
Explanation: This question tests unit conversion and working with scientific notation. First, understand the metric relationships: 1 decimeter (dm) = 0.1 meter (m) and 1 centimeter (cm) = 0.01 meter (m). Therefore, 1 decimeter = 10 centimeters.
Now, calculate 7.4 × 10² decimeters: 7.4 × 10² = 740 decimeters.
Finally, convert decimeters to centimeters: 740 decimeters × 10 centimeters/decimeter = 7,400 centimeters.
3. Mathematics Knowledge Sample Question:
If y=2x+3, what is the value of y when x = 5?
A. 10
B. 13
C. 15
D. 25
Answer:
The correct answer is B. 13
Explanation: This is a straightforward algebraic substitution question. To find the value of y when x = 5, substitute x = 5 into the equation y = 2x + 3:
y = 2(5) + 3 = 10 + 3 = 13.
As you can see, the Mathematics Knowledge subtest assesses basic arithmetic operations, algebraic formulas, unit conversions, and more. With 16 questions in 20 minutes on the CAT-ASVAB and 25 questions in 24 minutes on the P&P ASVAB, time management is crucial. Aim for approximately one minute per question. Success hinges on strong command of mathematical formulas and efficient calculation skills. Repetitive practice is the most effective way to improve your math skills.

Excelling in ASVAB Arithmetic Reasoning
The Arithmetic Reasoning subtest evaluates your ability to solve practical arithmetic problems encountered in everyday situations. Let’s examine some examples:
4. Arithmetic Reasoning Sample Question:
It took Sarah six minutes to drive to the post office, eight minutes to find parking, and five minutes to choose stationery; she then waited in line for seventeen minutes.
How many minutes passed from the time Sarah left her house until she completed her errand at the post office?
A. 39
B. 33
C. 36
D. 31
Answer:
The correct answer is 36.
Explanation: This is a straightforward time calculation problem. To find the total time, simply add up the duration of each activity: 6 minutes (driving) + 8 minutes (parking) + 5 minutes (stationery) + 17 minutes (waiting) = 36 minutes.
5. Arithmetic Reasoning Sample Question:
There are six printers at “Today’s news” newspaper, all printing at the same constant rate. When working together, the six printers can complete the printing of tomorrow’s newspaper within 12 hours.
If the owner wishes to reduce the printing time to 8 hours, how many other printers will he need to purchase, each with the same constant rate?
A. 1
B. 3
C. 6
D. 5
Answer:
The correct answer is B. 3
Explanation: This is a work-rate problem. Solve it in two steps:
(1) Calculate the individual work rate per printer: If 6 printers complete the job in 12 hours, their combined work rate is 1/12 of the newspaper per hour. Since each printer works at the same rate, each printer’s individual work rate is (1/12) / 6 = 1/72 of the newspaper per hour. This means one printer takes 72 hours to print the newspaper alone.
(2) Determine the number of printers needed for 8-hour printing time: Let ‘x’ be the number of printers needed. Using the formula: Work = Rate × Time. We want to complete 1 newspaper in 8 hours.
1 newspaper = x printers × (1/72 newspaper/printer-hour) × 8 hours
1 = x * (8/72)
1 = x * (1/9)
x = 9 printers
Since there are already 6 printers, the owner needs to purchase 9 – 6 = 3 additional printers.
6. Arithmetic Reasoning Sample Question:
A shirt is priced at $20 after a 20% discount.
What was its original price?
A. $24
B. $25
C. $28
D. $30
Answer:
The correct answer is B. $25
Explanation: This is a percentage discount problem. If the shirt costs $20 after a 20% discount, it means $20 represents 80% of the original price (100% – 20% = 80%). Let ‘X’ be the original price.
80% of X = $20
0.80X = $20
X = $20 / 0.80 = $25
Therefore, the original price of the shirt was $25.
Arithmetic Reasoning questions assess your ability to apply basic calculations and formulas while interpreting textual information. With 16 questions in 39 minutes (CAT-ASVAB) and 30 questions in 36 minutes (P&P ASVAB), the computerized version provides significantly more time per question, likely due to its adaptive difficulty. The key to success lies in quickly identifying the relevant data, formulating the correct equation, and choosing efficient problem-solving methods.

We now proceed to explore the five additional subtests that contribute to your composite scores. Refer to the table above to identify the sections relevant to your desired military position and prioritize your practice accordingly. We’ll start with General Science, which assesses your basic knowledge across various scientific disciplines.
ASVAB General Science: Testing Your Scientific Foundation
The General Science subtest provides a broad overview of both physical and biological sciences. This foundational assessment evaluates your knowledge in areas like Earth science, biology, chemistry, and physics. Let’s explore some sample questions:
13. General Science Sample Question:
What does an ammeter measure?
A. The voltage
B. The current
C. The power
D. The Resistance
Answer:
The correct answer is B. The current.
Explanation: An ammeter is an instrument used to measure electric current, which is measured in amperes (A). Voltage is measured by a voltmeter, power in watts, and resistance in ohms.
14. General Science Sample Question:
A ball thrown horizontally slows down due to:
A. Mass
B. Gravity
C. Inertia
D. Friction
Answer:
The correct answer is D. Friction.
Explanation: Let’s review the options:
- Mass: Mass is the amount of matter in an object and does not directly cause a horizontally thrown ball to slow down in this scenario.
- Gravity: Gravity acts vertically downwards, pulling the ball towards the Earth, but it primarily affects the vertical motion, not the horizontal slowing down.
- Inertia: Inertia is the tendency of an object to resist changes in its motion. While inertia keeps the ball moving forward, it doesn’t cause it to slow down.
- Friction: Friction is the force that opposes motion between surfaces in contact. Air resistance (a form of friction) and friction with the ground (if applicable) are the primary forces causing the ball to slow down horizontally.
15. General Science Sample Question:
Which of the following is NOT a mammal?
A. Whale
B. Dolphin
C. Bat
D. Shark
Answer:
The correct answer is D. Shark.
Explanation: This question tests your basic knowledge of biological classification.
- Whales, Dolphins, and Bats are all mammals. Mammals are warm-blooded vertebrates characterized by features like fur or hair, mammary glands for milk production, and typically giving birth to live young.
- Sharks are fish. Fish are aquatic vertebrates characterized by gills, fins, and typically a streamlined body. They are cold-blooded and reproduce differently from mammals.
General Science questions cover a wide range of scientific topics and require a broad, yet fundamental, understanding of physical, chemical, biological, and other common scientific fields. With 16 questions in 8 minutes (CAT-ASVAB) and 25 questions in 11 minutes (P&P ASVAB), you have approximately 30 seconds or less per question. A strong base of general scientific knowledge is crucial for quickly answering or narrowing down options.

ASVAB Mechanical Comprehension: Understanding Mechanical Principles
Mechanical Comprehension explores your understanding of principles related to simple machines, structural support, material properties, and mechanical motion.
16. Mechanical Comprehension Sample Question:
A hockey puck is sliding on an infinite plane of ice. Assume zero friction between the puck and the ice, as well as between the puck and the air.
What will affect the time required for the hockey puck to come to a full stop?
A. The puck’s weight
B. Gravity
C. The puck’s initial velocity
D. Nothing, it will never stop
Answer:
The correct answer is D. Nothing, it will never stop.
Explanation: This question tests your understanding of Newton’s Laws of Motion, particularly inertia and friction.
- Inertia: An object in motion tends to stay in motion with the same velocity unless acted upon by an external force (Newton’s First Law).
- Friction: Friction is a force that opposes motion between surfaces in contact.
In this scenario, we are told to assume zero friction. The only forces acting on the puck are its weight (due to gravity) and the normal force from the ice, which are vertical forces and do not oppose the horizontal motion. Since there is no friction or other horizontal force to oppose the puck’s motion, there is no force to cause it to decelerate or stop. Therefore, due to inertia, the puck will continue sliding indefinitely at a constant velocity.
17. Mechanical Comprehension Sample Question:
A perfectly smooth tube with a constant rate of water flow is given. A segment of the tube with two pressure gauges attached is shown in the diagram below.
Which pressure gauge will indicate a higher value?
A. 1
B. 2
C. Both will indicate the same
D. Impossible to answer
Answer:
The correct answer is C. Both will indicate the same.
Explanation: This question applies Bernoulli’s principle, which describes the relationship between pressure, velocity, and height for a fluid in motion. Bernoulli’s equation (simplified for this scenario) states:
P + ρgh + ½ρv² = constant
Where:
- P = pressure
- ρ = fluid density (constant for water)
- g = acceleration due to gravity (constant)
- h = height
- v = fluid velocity
Analysis:
- Constant Flow Rate and Tube Area: Since the tube has a constant cross-sectional area and the water flow rate is constant, the velocity of the water (v) remains constant throughout the tube.
- Identical Height: The pressure gauges are at the same height (h), meaning the potential energy term (ρgh) is the same at both points.
- Bernoulli’s Principle Application: Since velocity and height are constant at both gauges, according to Bernoulli’s principle, the pressure (P) must also be the same at both points to maintain the constant value of the equation.
Therefore, both pressure gauges will indicate the same pressure value.
18. Mechanical Comprehension Sample Question:
A pulley system is used to:
A. Increase friction
B. Increase electrical conductivity
C. Amplify sound
D. Change the direction or magnitude of a force
Answer:
The correct answer is D. Change the direction or magnitude of a force.
Explanation: Pulleys are simple machines designed to make it easier to lift heavy loads by changing the direction and/or magnitude of the force required.
- Change Direction: Pulleys can change the direction of force, for example, allowing you to pull down on a rope to lift an object upwards.
- Change Magnitude (Mechanical Advantage): Multiple pulleys in a system can create a mechanical advantage, reducing the amount of force needed to lift a load (though the distance you pull the rope increases).
Options A, B, and C are incorrect as they are not primary functions of a pulley system.
Mechanical Comprehension questions can test your knowledge of basic mechanical and physics principles or your ability to apply these principles to calculations, as seen in the pressure gauge example. With 16 questions in 20 minutes (CAT-ASVAB) and 25 questions in 19 minutes (P&P ASVAB), you need a strong grasp of fundamental formulas and concepts to answer knowledge-based questions quickly and have sufficient time for calculations. Our All-Inclusive ASVAB PrepPack includes a comprehensive mechanics guide, practice questions, and detailed explanations to help you master this section.

In which direction does conventional electric current flow in a wired circuit?
A. From the negative to the positive terminal
B. From the positive to the negative terminal
C. In the opposite direction of the positive-charge flow
D. In the same direction as the positive-charge flow
Answer:
The correct answer is B. From the positive to the negative terminal.
Explanation: This question tests your understanding of the convention for electric current direction.
- Conventional Current: By convention, electric current is defined as the flow of positive charge. It is depicted as flowing from the positive terminal to the negative terminal of a voltage source in a circuit.
- Electron Flow: In metallic conductors (like wires), the actual charge carriers are negatively charged electrons. Electrons flow in the opposite direction of conventional current, from the negative terminal to the positive terminal.
Options C and D are incorrect as they describe the opposite of conventional current flow. Option A describes the direction of electron flow, not conventional current.
20. Electronics Information Sample Question:
A force of 10 N (Newton) compresses two identical springs in parallel by 8 cm. What will be the total distance that four identical springs in series are compressed by the same 10 N force?
A. 32 cm
B. 16 cm
C. 20 cm
D. 64 cm
Answer:
The correct answer is D. 64 cm.
Explanation: This problem involves understanding spring behavior in parallel and series configurations.
-
Spring Constant and Hooke’s Law: The compression or extension of a spring is directly proportional to the force applied (Hooke’s Law). The spring constant (k) relates force (F) and displacement (x): F = kx.
-
Springs in Parallel: When identical springs are in parallel, the applied force is distributed equally among them. In the given scenario, with two springs in parallel and a 10 N force, each spring experiences 5 N of force and compresses by 8 cm.
-
Spring Constant Calculation: Using Hooke’s Law for a single spring in the parallel configuration: 5 N = k * 8 cm. Therefore, k = 5/8 N/cm.
-
Springs in Series: When identical springs are in series, the same force is applied to each spring in the chain. With four springs in series and a 10 N force, each spring will experience the full 10 N force.
-
Compression of a Single Spring under 10 N: Using Hooke’s Law with the calculated spring constant and 10 N force: 10 N = (5/8 N/cm) * x. Solving for x, we get x = 16 cm. Each spring in series compresses by 16 cm.
-
Total Compression in Series: Since there are four springs in series, the total compression is the sum of the compression of each spring: 4 springs * 16 cm/spring = 64 cm.
21. Electronics Information Sample Question:
A power supply outputs 15V at 3A. How much power does it deliver?
A. 5W
B. 18W
C. 45W
D. 50W
Answer:
The correct answer is C. 45W.
Explanation: This question tests your knowledge of basic electrical power calculations. Electrical power (P) is calculated using the formula:
P = V × I
Where:
- P = Power (in Watts)
- V = Voltage (in Volts)
- I = Current (in Amperes)
Given: Voltage (V) = 15V, Current (I) = 3A.
Power (P) = 15V × 3A = 45W.
Electronics Information questions assess your understanding of electricity principles and your ability to perform basic electrical calculations. With 16 questions in 8 minutes (CAT-ASVAB) and 20 questions in 9 minutes (P&P ASVAB), the time per question is very limited. Success requires a solid foundation in electricity concepts and ample practice with calculation-based questions to develop speed and accuracy.

Explanation: The alternator is a crucial component of a car’s electrical system. Its primary function is to generate electricity while the engine is running. This electricity serves two main purposes:
- Recharging the Battery: The alternator replenishes the battery’s charge, which is depleted during engine starting and when electrical accessories are used with the engine off.
- Powering Electrical Systems: The alternator supplies power to the car’s electrical systems while the engine is running, including lights, radio, air conditioning, and other accessories.
Options A, C, and D are incorrect. The starter motor starts the engine, the oil filter cleans the engine oil, and the radiator and cooling system cool the engine.
23. Auto and Shop Sample Question:
“Phillips” and “flathead” refer to types of what tool?
A. Wrenches
B. Pliers
C. Screwdrivers
D. Hammers
Answer:
The correct answer is C. Screwdrivers.
Explanation: “Phillips” and “flathead” are common types of screwdriver heads, distinguished by their tip shape:
- Phillips Screwdriver: Has a cross-shaped tip, designed to fit Phillips head screws.
- Flathead Screwdriver: Has a single, flat blade tip, designed for slotted screws.
Options A, B, and D are incorrect. Wrenches are used for tightening nuts and bolts, pliers are gripping and holding tools, and hammers are used for striking and driving objects.
24. Auto and Shop Sample Question:
A car’s “check engine” light illuminates. What tool is typically used to diagnose the cause?
A. OBD-II scanner
B. Torque wrench
C. Jumper cables
D. Tire pressure gauge
Answer:
The correct answer is A. OBD-II scanner.
Explanation: The “check engine” light indicates a problem within the car’s engine management or emissions systems. To diagnose the issue, mechanics use an OBD-II (On-Board Diagnostics II) scanner.
- OBD-II Scanner: This electronic tool plugs into the car’s OBD-II port (usually located under the dashboard). It reads diagnostic trouble codes (DTCs) stored by the car’s computer, which provide information about the nature and location of the problem triggering the “check engine” light.
Options B, C, and D are incorrect. A torque wrench measures tightening force, jumper cables are for jump-starting a car with a dead battery, and a tire pressure gauge measures tire inflation.
Auto and Shop questions require a broad knowledge base in both automotive and workshop domains. While some questions cover fundamental concepts, others may require more specific knowledge and practical understanding. With 11 questions in 7 minutes (Auto) and 6 minutes (Shop) on the CAT-ASVAB, and 25 questions in 11 minutes on the P&P ASVAB, efficient time management is crucial. While calculations are less frequent in this section, questions can be nuanced and require quick decision-making. Avoid spending excessive time on any single question and be prepared to make educated guesses when needed. Our All-Inclusive ASVAB PrepPack offers extensive Auto and Shop practice questions with detailed explanations to enhance your knowledge and test-taking strategies.

ASVAB Assembling Objects: Spatial Reasoning Skills
The Assembling Objects subtest is designed to assess your spatial awareness and visualization capabilities. You’ll be presented with images of disassembled objects and asked to determine how the parts fit together when assembled. This subtest is crucial for roles requiring spatial reasoning, assembly, or disassembly of equipment.
25. Assembling Objects Sample Question:
Which of the following figures shows all the objects assembled?
A
B
C
D
Answer:
The correct answer is B.
Explanation: Visually analyze the individual shapes and mentally combine them. Figure B is the only option that accurately depicts how all the component shapes would assemble together.
26. Assembling Objects Sample Question:
Which of the following figures includes all the following objects assembled? Note that the labeled (x,y,z) parts must be placed together.
A. A
B. B
C. C
D. D
E. E
Answer:
The correct answer is E.
Explanation: This question adds a constraint: labeled parts (x, y, z) must be connected. Examine each option, focusing on the correct joining of parts x, y, and z. Option E is the only figure that correctly assembles all shapes while adhering to the labeled part constraint.
27. Assembling Objects Sample Question:
Which of the following figures shows all the following objects assembled? Note that the labeled (A,B,C) parts must be placed together.
1
2
3
4
Answer:
The correct answer is B (figure 2).
Explanation: This question requires careful visual analysis and step-by-step deduction.
- Step 1: Focus on labeled ends ‘A’. Mentally connect the ends marked ‘A’. Only figures 1 and 2 show the ‘A’ ends joined.
- Step 2: Examine labeled ends ‘C’. Now, check which of the remaining figures (1 and 2) correctly joins the ends marked ‘C’. Only figure 2 shows the ‘C’ ends properly connected.
Therefore, figure 2 (option B) is the correct answer as it accurately assembles the object while respecting the labeled part constraints.
Assembling Objects questions are unique in their format, requiring strong spatial reasoning and visualization skills in both 2D and 3D contexts. With 16 questions in 16 minutes (CAT-ASVAB) and 25 questions in 15 minutes (P&P ASVAB), time is not overly generous but sufficient if you are well-prepared. Prior practice is essential to develop your ability to quickly visualize assembled objects and accurately choose the correct answer. Our All-Inclusive ASVAB PrepPack provides extensive Assembling Objects practice questions with detailed explanations to sharpen your spatial reasoning skills.
