Consider the question. Bill is trying to count the toddlers at his daycare, but they keep running around. He double-counts 8 toddlers and misses 3 who are hiding. If Bill thinks he counted 26 toddlers, how many are there really?
 What is the step-by-step reasoning process to arrive at the answer: 21?
First subtract the 8 toddlers Bill double - counted from his count: 26 toddlers - 8 toddlers = 18 toddlers. Then add the 3 toddlers he missed to find the real count: 18 toddlers + 3 toddlers = 21 toddlers.
