Question Analysis
This question involves a combination of adding and subtracting negative numbers in a single expression.
The main focus is on correctly applying the rules for each operation in the correct order.

Key Concept Explanation
Adding a positive number to a negative number on the number line means moving in the positive direction from the position of the negative number.
We subtract the smaller magnitude from the larger magnitude and take the sign of the number with the larger magnitude, and subtracting a negative number is equivalent to adding a positive number.

Step-by-Step Solution
First, we calculate -12 + 8. Since 12 > 8, we subtract 8 from 12 and take the negative sign, so 12 - 8 = 4.
