Let's solve each problem on the worksheet step by step. The goal is to
add integers, including both positive and negative numbers. We'll use the rules of integer addition:
Rules for Adding Integers:
1.
Same signs: Add absolute values, keep the common sign.
2.
Different signs: Subtract smaller absolute value from larger, keep the sign of the number with the larger absolute value.
