Adding And Subtracting Integers - Quiz

Questions and Answers
  • 1. 

    (+6) + (+5)

    • A.

      -1

    • B.

      1

    • C.

      10

    • D.

      11

    Correct Answer
    D. 11
    Explanation
    When adding two positive numbers, the result is always positive. In this case, adding +6 and +5 gives us +11. Since the question asks for the result after subtracting 1, we subtract 1 from +11, which gives us the final answer of 11.

    Rate this question:

  • 2. 

    =(19) - (-3) =

    • A.

      -22

    • B.

      16

    • C.

      22

    • D.

      24

    Correct Answer
    C. 22
    Explanation
    The given expression is subtracting a negative number from a positive number. When subtracting a negative number, it is equivalent to adding the positive value of that number. Therefore, (-3) becomes 3 and the expression simplifies to 19 + 3 = 22.

    Rate this question:

  • 3. 

    (-43) - (-19) =

    • A.

      -24

    • B.

      24

    • C.

      14

    • D.

      21

    Correct Answer
    A. -24
    Explanation
    When subtracting a negative number, it is equivalent to adding its positive counterpart. Therefore, (-43) - (-19) can be rewritten as (-43) + 19. Adding these two numbers gives us -24.

    Rate this question:

  • 4. 

    (+39) - (+15) =

    • A.

      -22

    • B.

      -24

    • C.

      22

    • D.

      24

    Correct Answer
    D. 24
    Explanation
    The given expression is a subtraction problem with positive and negative numbers. When subtracting a positive number from another positive number, the result is positive. Therefore, (+39) - (+15) equals 24.

    Rate this question:

  • 5. 

    (-14) - (-5) =

    • A.

      19

    • B.

      9

    • C.

      -9

    • D.

      -19

    Correct Answer
    C. -9
    Explanation
    When subtracting a negative number, it is equivalent to adding its positive counterpart. In this case, (-14) - (-5) can be rewritten as (-14) + 5. Adding 5 to -14 gives us -9. Therefore, the correct answer is -9.

    Rate this question:

  • 6. 

    (-29) - (-24) =

    • A.

      -5

    • B.

      5

    • C.

      -15

    • D.

      15

    Correct Answer
    A. -5
    Explanation
    When subtracting a negative number from another negative number, we can rewrite the equation as (-29) + 24. Adding a negative number is the same as subtracting a positive number, so (-29) + 24 = -5. Therefore, the correct answer is -5.

    Rate this question:

  • 7. 

    (-19) + (-16) =

    • A.

      30

    • B.

      35

    • C.

      -35

    • D.

      20

    Correct Answer
    C. -35
    Explanation
    The sum of two negative numbers, -19 and -16, is always negative. In this case, the sum is -35.

    Rate this question:

  • 8. 

    (13) + (-2)

    • A.

      15

    • B.

      11

    • C.

      -11

    • D.

      15

    Correct Answer
    B. 11
    Explanation
    When we add a positive number and a negative number, we subtract the smaller number from the larger number and assign the sign of the larger number to the result. In this case, 13 is a positive number and -2 is a negative number. When we subtract 2 from 13, we get 11. Since 13 is the larger number and it is positive, the result is positive 11.

    Rate this question:

  • 9. 

    (+8) + (+7)

    • A.

      5

    • B.

      -15

    • C.

      15

    • D.

      3

    Correct Answer
    C. 15
    Explanation
    When adding two positive numbers, the result is always positive. In this case, adding 8 and 7 gives us 15, which is a positive number.

    Rate this question:

  • 10. 

    (-6) + (+25)

    • A.

      -19

    • B.

      31

    • C.

      -31

    • D.

      19

    Correct Answer
    D. 19
    Explanation
    The given expression (-6) + (+25) can be simplified by adding the two numbers together. When adding a positive number and a negative number, we subtract the smaller absolute value from the larger absolute value and use the sign of the number with the larger absolute value. In this case, the absolute value of -6 is smaller than the absolute value of +25, so we subtract 6 from 25 and use the sign of 25, which is positive. Therefore, (-6) + (+25) equals 19.

    Rate this question:

  • 11. 

    (+8) - (+2) =

    • A.

      6

    • B.

      -6

    • C.

      10

    • D.

      -10

    Correct Answer
    A. 6
    Explanation
    The given expression is (+8) - (+2). When subtracting a positive number from another positive number, we can simply subtract the two numbers and keep the positive sign. Therefore, (+8) - (+2) equals 6.

    Rate this question:

  • 12. 

    (+39) - (+15)

    • A.

      -24

    • B.

      24

    • C.

      42

    • D.

      -42

    Correct Answer
    B. 24
    Explanation
    The given expression is a subtraction of two positive numbers. When we subtract a positive number from another positive number, the result will always be positive. Therefore, the correct answer is 24.

    Rate this question:

  • 13. 

    (+7) + (-7) =

    • A.

      0

    • B.

      14

    • C.

      -14

    • D.

      7

    Correct Answer
    A. 0
    Explanation
    When we add a positive number and a negative number with the same absolute value, the result is always zero. In this case, +7 and -7 have the same absolute value of 7. Therefore, when we add them together, the result is 0.

    Rate this question:

  • 14. 

    (-8) + (-3) =

    • A.

      11

    • B.

      -11

    • C.

      5

    • D.

      -5

    Correct Answer
    B. -11
    Explanation
    The given expression (-8) + (-3) is a sum of two negative numbers. When adding two negative numbers, we add their absolute values and keep the negative sign. In this case, the absolute value of -8 is 8 and the absolute value of -3 is 3. Adding these values gives us 11. However, since both numbers are negative, the result is also negative. Therefore, the correct answer is -11.

    Rate this question:

  • 15. 

    (-8) -(-2)

    • A.

      10

    • B.

      6

    • C.

      -6

    • D.

      -10

    Correct Answer
    C. -6
    Explanation
    When subtracting a negative number, it is equivalent to adding the positive value of that number. In this case, (-8) - (-2) can be rewritten as (-8) + 2. Adding -8 and 2 gives us -6, which is the correct answer.
