That's your choice, but in my experience that simply means that you don't end up able to apply the knowledge you think you have acquired by reading about a topic.
That might be fine for you, but it's an inherent limitation in reading about something, rather than actually engaging in it.
I've edited my original comment to make a comparison, and expand on why I say this.
But to take you up on this - some exercises have answers in the text. You could do just those. Other exercises don't have the answers, just like code that you write doesn't already exist. When you write the code you then have the ability to check that it does what it's supposed to do.
The idea of having exercises without answers it to foster the ability to understand when your answers are right. Most of the time it's easy to know if you got the right answers, but it's finding the answer that's the challenge. If you choose not to learn this topic, fine, that's your choice. My comment just says: don't expect to understand the material at anything other than a superficial level if all you do is read about it.
As it says in the quoted section: One does not get fit by merely looking at a treadmill.
