Let's solve each problem step by step.

  1. For the expression \( 12 + (-7) \): \[ 12 - 7 = 5 \] So, the answer is 5.

  2. For the expression \( -3 - (-8) \): \[ -3 + 8 = 5 \] So, the answer is 5.

  3. For the expression \( 4 + (-7) \): \[ 4 - 7 = -3 \] So, the answer is -3.

To summarize the answers:

  1. \( 12 + (-7) = 5 \)
  2. \( -3 - (-8) = 5 \)
  3. \( 4 + (-7) = -3 \)
