What is 40 - 16 ÷ 4 ?
- A.
6
- B.
36
Correct Answer
B. 36Explanation
To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS). First, we divide 16 by 4, which equals 4. Then, we subtract 4 from 40, resulting in 36. Therefore, the correct answer is 36.Rate this question:

What is 8 x (6 + 4)?
- A.
50
- B.
80
Correct Answer
B. 80Explanation
The given expression is 8 multiplied by the sum of 6 and 4. Using the order of operations, we first calculate the sum inside the parentheses, which is 10. Then, we multiply 8 by 10, resulting in 80. Therefore, the correct answer is 80.Rate this question:

What is 86 - 9 x 9?
- A.
5
- B.
693
Correct Answer
A. 5Explanation
The correct answer is 5 because according to the order of operations (PEMDAS/BODMAS), we need to perform the multiplication before subtraction. So, 9 multiplied by 9 equals 81. Then, subtracting 81 from 86 gives us 5.Rate this question:

Use a calculator to evaluate 16974 - (18 x 45)
- A.
16 164
- B.
763 020
Correct Answer
A. 16 164Explanation
To evaluate the given expression, we need to perform the multiplication operation first. 18 multiplied by 45 equals 810. Then, we subtract 810 from 16,974, resulting in 16,164. Therefore, the correct answer is 16,164.Rate this question:

Use a calculator to evaluate 8537 + 4825 ÷ 25
- A.
534
- B.
8730
Correct Answer
B. 8730Explanation
To evaluate the expression 8537 + 4825 ÷ 25, we need to follow the order of operations (PEMDAS/BODMAS). First, we divide 4825 by 25, which equals 193. Then, we add 8537 to 193, which equals 8730. Therefore, the correct answer is 8730.Rate this question:

Which of the following equals to 25?
- A.
4 x (7 - 2) + 1
- B.
4 x (7 - 2 + 1)
- C.
4 X 7 - (2 + 1)
Correct Answer
C. 4 X 7 - (2 + 1)Explanation
The given expression is 4 x 7 - (2 + 1). According to the order of operations (PEMDAS/BODMAS), we need to solve the parentheses first. The sum inside the parentheses is 2 + 1, which equals 3. Thus, the expression becomes 4 x 7 - 3. Multiplying 4 by 7 gives us 28. Finally, subtracting 3 from 28 results in 25. Therefore, the expression 4 x 7 - (2 + 1) equals 25.Rate this question:

Where would you add brackets to make this equation true: 6 x 2 + 8 ÷ 4 = 15
- A.
Around the 6 x 2
- B.
Around the 2 + 8
- C.
Around the 8 ÷ 4
Correct Answer
B. Around the 2 + 8Explanation
To make the equation true, we need to determine the order of operations. According to the PEMDAS rule, we must perform the multiplication before addition. Therefore, adding brackets around the 2 + 8 will ensure that the addition is done before the multiplication. This way, the equation becomes (6 x 2) + (8 ÷ 4) = 15, which is true.Rate this question:
