Section 1: Number Operations and Whole Numbers
Place Value, Addition, Subtraction, Multiplication, Division, and Word Problems (Q1-Q15)
Q1: In the whole number 274,518, what is the value of the digit 7?
A. Seven
B. Seventy
C. Seven hundred
D. Seventy thousand **[CORRECT]**
Correct Answer: D
Rationale: The digit 7 is in the ten thousands place, meaning its value is 7 x 10,000 = 70,000, or seventy thousand. Option A
represents the face value only. Option B would be correct if 7 were in the tens place. Option C would apply if 7 were in the
hundreds place. Place value is determined by position relative to the decimal point per NCCER Module 00102-15.
Q2: A construction crew needs to add the following material counts: 1,247 + 3,586 + 2,139. What is the sum?
A. 6,872
B. 6,962
C. 6,972 **[CORRECT]**
D. 7,072
Correct Answer: C
Rationale: 1,247 + 3,586 = 4,833; then 4,833 + 2,139 = 6,972. Option A fails to carry properly in the hundreds column. Option B
drops the tens digit. Option D adds an extra 100 from a carrying error. Addition of whole numbers is foundational in NCCER
construction math for totaling material quantities.
Q3: A subcontractor has 8,452 lbs of steel on site and delivers 3,187 lbs more. After using 5,240 lbs on a
project, how many pounds remain?
A. 6,399 lbs **[CORRECT]**
B. 5,269 lbs
C. 6,409 lbs
D. 5,399 lbs
Correct Answer: A
Rationale: First add: 8,452 + 3,187 = 11,639 lbs. Then subtract: 11,639 - 5,240 = 6,399 lbs. Option B subtracts before adding.
Option C has a carrying error in the final subtraction. Option D combines both errors. NCCER Module 00102-15 emphasizes
identifying key information and determining operations step by step.
Q4: What is the product of 347 and 26?

, NCCER Module 00102-15 Exam Verified Answers
A. 8,822
B. 9,022 **[CORRECT]**
C. 9,122
D. 9,222
Correct Answer: B
Rationale: 347 x 6 = 2,082 and 347 x 20 = 6,940; then 2,082 + 6,940 = 9,022. Option A results from an error in the partial
product of 347 x 20. Option C adds an extra 100. Option D doubles the error. The product is the answer to multiplication, a core
NCCER concept for calculating material quantities.
Q5: A framing crew must divide 2,847 linear feet of lumber equally among 9 workstations. How many feet per
workstation, and what is the remainder?
A. 316 feet with a remainder of 3 **[CORRECT]**
B. 316 feet with a remainder of 4
C. 326 feet with a remainder of 3
D. 316 feet with a remainder of 5
Correct Answer: A
Rationale: 2, = 316 with remainder 2,847 - (9 x 316) = 2,847 - 2,844 = 3. The dividend is 2,847, divisor is 9, quotient is
316, remainder is 3. Option B miscalculates the remainder. Option C has an error in the quotient. Division terms are defined in
NCCER Module 00102-15.
Q6: Which of the following correctly defines an equation?
A. A mathematical statement showing two expressions that are not equal
B. A mathematical statement indicating equality between two expressions **[CORRECT]**
C. A type of measurement used in construction layout
D. A tool used to calculate area and volume
Correct Answer: B
Rationale: An equation is a mathematical statement indicating equality between two expressions, as defined in NCCER Module
00102-15. Option A describes an inequality. Option C confuses equation with a unit of measurement. Option D confuses equations
with formulas. Understanding equations is essential for solving construction math problems involving unknowns.
Q7: Solve using the correct order of operations: 8 + 4 x 3 -
A. 15
B. 17 **[CORRECT]**
C. 21
D. 9
Correct Answer: B
Rationale: PEMDAS: First 4 x 3 = 12 and = 3, then 8 + 12 - 3 = 17. Option A (15) performs all operations left to right
without regard to order. Option C adds before multiplying. Option D subtracts before dividing. Order of operations is critical in
NCCER construction math.
Q8: Which term describes the result of a subtraction operation?
A. Sum
B. Product
C. Quotient
