Question 1
Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots
of the whole number?
• A) ±2.3
• B) ±3.3
• C) ±4
• D) ±5
Answer: D) ±5
Rationale: The only whole number in the set is 25. The square roots of 25 are 5
and -5 because 5 × 5 = 25 and (-5) × (-5) = 25. The other numbers (3.3, -2.3, -16)
are not whole numbers.
Question 2
Given the following expression: 4 + 7 × (6 - 3)². What is the answer using proper
order of operations?
• A) 25
• B) 46
• C) 67
• D) 99
Answer: C) 67
Rationale: Using PEMDAS: Parentheses first: (6-3)=3. Then Exponents: 3²=9. Then
Multiplication: 7×9=63. Finally Addition: 4+63=67.
,Question 3
Given the following expression: 5 × (30 - 27)² + 4. What is the correct answer using
the proper order of operations?
• A) 34
• B) 49
• C) 65
• D) 81
Answer: B) 49
Rationale: Using PEMDAS: Parentheses first: (30-27)=3. Then Exponents: 3²=9.
Then Multiplication: 5×9=45. Finally Addition: 45+4=49.
Question 4
What is the value of x in this equation? 2x + 3 = 13
• A) 5
• B) 10
• C) 76
• D) 106
Answer: A) 5
Rationale: Subtract 3 from both sides: 2x = 10. Divide both sides by 2: x = 5.
Question 5
Which property states that 0 + a = a?
• A) Identity property
• B) Inverse property
, • C) Commutative property
• D) Associative property
Answer: A) Identity property
Rationale: The identity property of addition states that adding 0 to any number
leaves it unchanged. The multiplicative identity is 1.
Question 6
What is the solution to -32 ÷ 8?
• A) -4
• B) -8
• C) 4
• D) 8
Answer: A) -4
Rationale: Dividing a negative number by a positive number yields a negative
result. -32 ÷ 8 = -4.
Question 7
What is the sum of the integers in the set {16, -3, 8, -5}?
• A) 16
• B) 18
• C) 26
• D) 32
Answer: A) 16
Rationale: Add all integers: 16 + (-3) + 8 + (-5) = 16 - 3 + 8 - 5 = 16.
, Question 8
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when
adding together only the whole numbers?
• A) 5.5
• B) 11
• C) 12.5
• D) 15
Answer: D) 15
Rationale: Whole numbers are non-negative integers. From the set, the whole
numbers are 10 and 5. Their sum is 10 + 5 = 15. The negative numbers (-4, -4.5)
are not whole numbers, and 2.5 is a decimal.
Question 9
What is the greatest common factor of 132 and the square root of 121 using
prime factorization?
• A) 1
• B) 2
• C) 10
• D) 11
Answer: D) 11
Rationale: √121 = 11. Prime factorization of 132 = 2² × 3 × 11. The common factor
between 132 and 11 is 11.
Question 10
What is the greatest common factor of 24 and 84 using prime factorization?
