    • 9

    • -9

    • 5

    • -5

    Correct Answer
    A. -9
    Explanation
    The correct answer is -9 because when we subtract 7 from -2, we get -9.

    Rate this question:

    9-2-6-7

    • 1

    • 7

    • -7

    • -6

    Correct Answer
    A. -6
    Explanation
    The given sequence is 9-2-6-7. To find the next number in the sequence, we can observe that the first number is subtracted by 7, the second number is subtracted by 4, and the third number is subtracted by 1. Following this pattern, the fourth number should be subtracted by -2, resulting in -6. Therefore, the answer is -6.

  • 4. 

    -5+(-20)=

    • -25

    • 25

    • 15

    • -15

    Correct Answer
    A. -25
    Explanation
    The given expression involves adding a negative number (-5) and another negative number (-20). When we add two negative numbers, the result is always a negative number. Therefore, the correct answer is -25.

    Rate this question:

  • 5. 

    5-(-6)=

    • 11

    • -1

    • 1

    • -11

    Correct Answer
    A. 11
    Explanation
    The given equation is 5-(-6). When subtracting a negative number, it is equivalent to adding the positive of that number. So, -(-6) becomes +6. Therefore, 5+6 equals 11.

  • 6. 

    Calculati:-2+7

    • 5

    • -5

    • 9

    • -9

    • O

    • 14

    • 2

    • -14

    Correct Answer
    A. -14
    Explanation
    The given equation is -7 - 7. When subtracting two negative numbers, the result is negative. Therefore, -7 - 7 equals -14.

    Rate this question:

  • 8. 

    -4-(-2+5)+(7-8)

    • -8

    • 8

    • -5

    • -3

    Correct Answer
    A. -8
    Explanation
    The given expression involves addition, subtraction, and multiplication of numbers. To solve it, we can start by simplifying the parentheses first. Inside the parentheses, -2+5 equals 3 and 7-8 equals -1. So the expression becomes -4-3+(-1). Next, we can perform the subtraction from left to right. -4-3 equals -7 and -7+(-1) equals -8. Therefore, the correct answer is -8.

    Rate this question:

  • 9. 

    -5-2+11=

    • -4

    • 4

    • 18

    • -18

    Correct Answer
    A. 4
    Explanation
    The given equation is solved by following the order of operations (PEMDAS/BODMAS). First, we subtract 2 from -5 which gives us -7. Then, we add 11 to -7 which gives us 4. Therefore, the correct answer is 4.

    Rate this question:

  • 10. 

    -3-(8-10)+11=

    • -10

    • 10

    • -9

    • 8

    Correct Answer
    A. 10
    Explanation
    The expression is simplified by first evaluating the parentheses, which results in (8-10) being equal to -2. Then, the expression is simplified further by performing the subtraction and addition operations from left to right. Therefore, -3 - (-2) + 11 is equal to -3 + 2 + 11, which simplifies to 10.
