The document provides steps for adding integers using a number line. It explains that to add integers, you start at 0 on the number line and walk the number of steps in the direction of the sign for each number being added. Any positives and negatives cancel each other out as you walk. It then works through examples of 6 + 10 and 2 + 6 to arrive at answers of -4 and +4 respectively.
