    • C.

      6

    Correct Answer
    B. -12
    Explanation
    The given expression is a subtraction problem, where you subtract 3 from 9. Since both numbers have a negative sign, when you subtract a negative number from a positive number, it is equivalent to adding the absolute values of the numbers. Therefore, the result of -9 + -3 is -12.

    • C.

      1

    Correct Answer
    C. 1
    Explanation
    The given expression is a simple addition problem. When we add 11 and -10, we get a sum of 1. Therefore, the correct answer is 1.

    • B.

      17

    • C.

      -17

    Correct Answer
    B. 17
    Explanation
    The given expression is 12 - (-5). When subtracting a negative number, it is the same as adding its positive counterpart. Therefore, -(-5) becomes +5. So, the expression simplifies to 12 + 5, which equals 17.

    Rate this question:

    • B.

      -5

    • C.

      5

    Correct Answer
    A. 1
    Explanation
    The given expression involves finding the absolute value of -3, which is 3, and then adding -2 to it. Therefore, the result is 3 + (-2) = 1.

    Rate this question:

  • 5. 

    -9 - 4

    • A.

      - 5

    • B.

      - 13

    • C.

      5

    Correct Answer
    B. - 13
    Explanation
    The given question requires subtracting -4 from -9. When subtracting a negative number, it is equivalent to adding the positive value of that number. Therefore, subtracting -4 from -9 is the same as adding 4 to -9, which equals -13.

    Rate this question:

  • 6. 

    -5 * 4

    • A.

      -9

    • B.

      20

    • C.

      -20

    Correct Answer
    C. -20
    Explanation
    The given expression is -5 multiplied by 4. When we multiply a negative number by a positive number, the product is always negative. Therefore, -5 multiplied by 4 equals -20.

    Rate this question:

  • 7. 

    36 / -6

    • A.

      -6

    • B.

      6

    • C.

      30

    Correct Answer
    A. -6
    Explanation
    When we divide 36 by -6, we are essentially looking for the number that, when multiplied by -6, gives us 36. In this case, -6 multiplied by -6 equals 36, so -6 is the correct answer.

    Rate this question:

  • 8. 

    0 / -15

    • A.

      15

    • B.

      0

    • C.

      1

    Correct Answer
    B. 0
    Explanation
    The given answer is 0 because when you divide 0 by any number, the result is always 0. In this case, when you divide 0 by -15, the result is 0. Similarly, when you divide 0 by 15 or 0 or 1, the result is still 0. Therefore, the answer is 0.

    Rate this question:

  • 9. 

    What is the mean of the following set of numbers?-8, 1, 2, -10, 0,

    • A.

      -15

    • B.

      3

    • C.

      -3

    Correct Answer
    C. -3
    Explanation
    The mean of a set of numbers is found by adding up all the numbers in the set and then dividing the sum by the total number of numbers. In this case, the sum of the numbers -8, 1, 2, -10, 0, -15, 3 is -27. Since there are 7 numbers in the set, the mean is -27 divided by 7, which is approximately -3.

    Rate this question:

  • 10. 

    | -12| + | 4|

    • A.

      -8

    • B.

      8

    • C.

      16

    Correct Answer
    C. 16
    Explanation
    The expression | -12| + | 4| can be simplified by finding the absolute values of -12 and 4, which are both positive. Therefore, the expression simplifies to 12 + 4, which equals 16.
