Well, let's imagine numbers as friends playing on a see-saw. When we add 74 and 13 together, it's like lifting one friend higher on the see-saw, making the total 87. Then, when we subtract 13 from 87, it's like bringing that friend back down to the same level as the other, which gives us back our original number of 74. It's all about balancing the numbers, just like friends on a see-saw!
