Answers

  1. =\dfrac{−12}{−4−8}

    =1

  2. =−8 \times -17

    =136

  3. =−5+(7)

    =−5+7

    =2

  4. =4−(1)^2

    4−1

    =3

  5. = -8 + 70

    = 62

  6. Remember that a negative sign is only part of the base of an exponent if it is inside parentheses with the base.

    -4^2 - (-3)^2

    =−(4 \cdot 4) - (-3 \cdot -3)

    = -16 - 9

    = - 25

  7. (-5 + 7) -9 \times 5

    =−5 + 7 - 45

    2 - 45

    =-43
