I'll give you a question, please answer with step-by-step reasoning process.
Susan has 21 cats and Bob has 3 cats. If Susan gives Robert 4 of her cats, how many more cats does Susan have than Bob?

14
After giving away four of her cats, Susan has 21 - 4 = 17.

Susan has 17 - 3 = 14 more cats than Bob.

The answer is 14
