Here are the solutions to the problems:

Part g· 2 steps

Find 9+(−11)9 + (-11)

  1. Rewrite the expression.

    Adding a negative number is equivalent to subtracting the number.

    9+(−11)=9−119 + (-11) = 9 - 11

  2. Perform the subtraction.

    9−11=−29 - 11 = -2

    The answer is −2\boxed{-2}.

Part h-3

Find 6+(−9)6 + (-9)

  1. Rewrite the expression.

    6+(−9)=6−96 + (-9) = 6 - 9

  2. Perform the subtraction.

    6−9=−36 - 9 = -3

    The answer is −3\boxed{-3}.

Part h(i)-13

Find 3+(−16)3 + (-16)

  1. Rewrite the expression.

    3+(−16)=3−163 + (-16) = 3 - 16

  2. Perform the subtraction.

    3−16=−133 - 16 = -13

    The answer is −13\boxed{-13}.

    j) Find 8+(−19)8 + (-19)

  3. Rewrite the expression.

    8+(−19)=8−198 + (-19) = 8 - 19

  4. Perform the subtraction.

    8−19=−118 - 19 = -11

    The answer is −11\boxed{-11}.
