Database of answers/explanations for high school math/science text books


Recommended Posts

Hi all! I wanted to recommend a relatively new website, Slader.com. It has answers (with step-by-step explanations) for many of the popular math and science textbooks used in high school (for example, lots of the Saxon, Stewart, and Larson titles).

 

It also has some english and history too, but the main focus is math and science.

Just curious since I see you must register to actually see solutions and I didn't so I don't know what the next step would be, but is this one of those affiliate sites? You know,where people establish them and then get paid for every time someone registers? Or maybe I missed where there is a review/comparison of books. I only checked in to see calculus since I was familiar with one of those books.

I wondered the same thing. I browsed but did not register.

As far as I know, it's not an affiliate site. It looks like it gets its money via advertising (like all other websites) and by having students buy "points". (You can look at the answers to the questions for free, but if you want to look at step-by-step explanations, you need to spend points.) Free points can also be earned (see the "slader for free" button at the top of the page).

 

Prices:

* 5 solutions per day = $2/month or 1500 points

* 15 solutions per day = $3/month or 2250 points

* 30 solutions per day = $4/month or 3000 points

* one-time purchase of 20 solution views = $1 or 750 points

* one-time purchase of 50 solution views = $2 or 1500 points

 

For math and science (I've mostly been looking at geometry and calculus), there are answer keys with explanations for a huge range of textbooks. The answer keys are in various stages of completeness, but a lot are almost totally complete.

 

For english and history, there are fewer books, and instead of answer keys (which wouldn't make sense), there are discussion boards. However, these don't seem very active yet, since the school year just started in most places, and this website is pretty new.

 

PS: If anyone tries the paid subscription method, try this promo code: liz. It should give you a free 30-day subscription for 15 solutions per day. And let me know if it's worth it -- I've only been using the website for free so far.
