      -45

    • D.

      35

    Correct Answer
    A. -35
    Explanation
    The given equation is a subtraction problem. When subtracting a positive number from a negative number, we can think of it as adding the opposite of the positive number. In this case, we are subtracting 10 from -25, which is the same as adding -10 to -25. The sum of -25 and -10 is -35.

      -3

    • C.

      3

    • D.

      -2

    Correct Answer
    D. -2
    Explanation
    The given expression involves adding three numbers: -3, -9, and 10. When we add -3 and -9, we get -12. Then, when we add -12 and 10, we get -2. Therefore, the correct answer is -2.

    Rate this question:

  • 5. 

    15 - (-5) =

    • A.

      -10

    • B.

      20

    • C.

      10

    • D.

      -20

    Correct Answer
    B. 20
    Explanation
    The given equation is a subtraction problem. When subtracting a negative number, it is equivalent to adding the positive value of that number. Therefore, 15 - (-5) can be rewritten as 15 + 5, which equals 20.

    Rate this question:

  • 6. 

    - 12 - (-6) =

    • A.

      -18

    • B.

      6

    • C.

      18

    • D.

      -6

    Correct Answer
    D. -6
    Explanation
    The given expression is subtracting a negative number from a positive number. When subtracting a negative number, it is the same as adding the positive value. Therefore, the calculation becomes 12 + 6, which equals 18. However, since the negative sign is still present in the expression, the final answer is -18.

    Rate this question:

  • 7. 

    - 8 - 6 + 14 =

    • A.

      0

    • B.

      1

    • C.

      2

    • D.

      -1

    Correct Answer
    A. 0
    Explanation
    The given expression can be simplified by following the order of operations, which states that we should first perform any calculations inside parentheses, then perform any multiplications or divisions from left to right, and finally perform any additions or subtractions from left to right. In this case, there are no parentheses or multiplications/divisions, so we can simply evaluate the expression from left to right. Starting with 8 minus 6 equals 2, and then adding 14 gives us a final result of 16. Therefore, the correct answer is 16.

    Rate this question:

  • 8. 

    X + (-5) + (-9) = 0 Tentukan nilai x ?

    • A.

      13

    • B.

      4

    • C.

      -14

    • D.

      14

    Correct Answer
    D. 14
    Explanation
    The correct answer is 14 because when we simplify the equation, we get x - 5 - 9 = 0. By combining like terms, we have x - 14 = 0. To isolate x, we add 14 to both sides of the equation, resulting in x = 14.

    Rate this question:

  • 9. 

    5 x ( 8 - (-3)) =

    • A.

      60

    • B.

      55

    • C.

      45

    • D.

      43

    Correct Answer
    B. 55
    Explanation
    To solve this equation, we first need to simplify the expression within the parentheses. The subtraction inside the parentheses can be rewritten as addition by changing the sign of the negative number. So, 8 - (-3) becomes 8 + 3, which equals 11. Then, we multiply 5 by 11, which gives us 55. Therefore, the correct answer is 55.

    Rate this question:

  • 10. 

    P + 4 x 5 = 15 Berapakah nilai p?

    • A.

      -5

    • B.

      1

    • C.

      -1

    • D.

      5

    Correct Answer
    A. -5
    Explanation
    To find the value of p, we need to solve the equation p + 4 x 5 = 15. First, we simplify the expression 4 x 5, which equals 20. Then, we subtract 20 from both sides of the equation to isolate p. This gives us p = 15 - 20, which simplifies to p = -5. Therefore, the value of p is -5.

    Rate this question:

  • 11. 

    -16 x m = 112 Maka nilai m ?

    • A.

      6

    • B.

      -6

    • C.

      -7

    • D.

      7

    Correct Answer
    C. -7
    Explanation
    To find the value of m, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by -16. This gives us m = 112 / -16, which simplifies to m = -7. Therefore, the value of m that satisfies the equation -16 x m = 112 is -7.

    Rate this question:

  • 12. 

    120 : 20 + 4 - p = 5 Berapakah nilai p ?

    • A.

      5

    • B.

      4

    • C.

      6

    • D.

      7

    Correct Answer
    A. 5
    Explanation
    The given equation is 120 : 20 + 4 - p = 5. To find the value of p, we need to simplify the equation. First, we divide 120 by 20 which gives us 6. Then, we add 4 to get 10. Finally, we subtract p from 10 and set it equal to 5. Solving for p, we find that p is equal to 5.

    Rate this question:

  • 13. 

    3 + 45 : 5 x 2 =

    • A.

      7,2

    • B.

    • C.

      21

    • D.

      23

    Correct Answer
    C. 21
    Explanation
    The given expression involves addition, division, and multiplication. According to the order of operations (PEMDAS/BODMAS), we need to perform the division and multiplication before addition. First, we divide 45 by 5, which gives us 9. Then, we multiply 9 by 2, resulting in 18. Finally, we add 3 to 18, giving us the final answer of 21.

      8

    • D.

      3

    Correct Answer
    C. 8
    Explanation
    The given equation is 35 : 7 + 5 - 2. According to the order of operations (PEMDAS/BODMAS), we first perform the division operation, which gives us 5. Then, we add 5 to 7, resulting in 12. Finally, we subtract 2 from 12, which equals 10. Therefore, the correct answer is 10.

    Rate this question:

  • 15. 

    12 + 6 - 2 + 4 =

    • D.

      19

    Correct Answer
    A. 20
    Explanation
    The equation is solved using the order of operations, which states that you should perform multiplication and division before addition and subtraction. So, first, you add 12 and 6, which gives you 18. Then, you subtract 2 from 18, which gives you 16. Finally, you add 4 to 16, which equals 20.
