What is normal?

Culture dictates what normative behavior is. And culture is inescapable. It's even in these words that I type. But try this: close your eyes. For a moment, ignore the past, ignore the future, feel where you are right now. Quiet the mind. Pursue your truth. And make that your normal.


I thought everything on Slader was free!

All high school textbook solutions on Slader are free for all students. So is Slader Q&A.

As of 2020, unlimited textbook solutions in upper level, college textbooks are only available to users who subscribe to Slader College+. (You can still get 5 free solutions per book every month without a subscription) We understand how stressful school can be, and we know that you’ve got bills to pay too. We are committed to ensuring Slader is more affordable than the alternatives. And we will work hard every day to make sure your investment in our product is worth it. We appreciate your support.

What does the Slader College+ subscription get me?

The College+ subscription will give you unrestricted access to a large library of upper-level College content and solutions as well as an ad-lite experience for distraction-free studying.

This book used to be free. Why do I have to pay now?

Slader includes hundreds of thousands of expert solutions in thousands of upper level books. As of 2020, some of these books are now labeled as Slader College+. In order to continue producing upper-level solutions, we ask that you subscribe to Slader College+. This will give you unlimited access to all premium solutions, and help to ensure we can continue to produce high-quality solutions for your hardest classes.

I’m already paying for premium. Why can't I access this book?

Our premium subscription is different from our new Slader College+ subscription. Premium subscriptions provide you with an ad-lite experience, whereas the Slader College+ subscription provides you with this experience AND unrestricted access to all of our upper-level College solutions.

What are the Star ratings?

A solution's star allows users to quickly identify high-quality solutions and solutions that need a bit more work. Give a solution a star rating. If it is an excellent solution and has helped you, give it 5 stars. Only give incorrect solutions 1 star ratings.

Also: be nice. Don't down-vote someone else's solution and up-vote yours just to earn the top spot when the other solution is a-okay. Common courtesy folks! If you notice someone abusing the rating system, please let us know at
