There are thousands of books that have been publish over the years, so we try and locate what we can and add. We may have no located or considered one. This is why we provide for you to add your textbook, so that our database will grow and help out other people around the word.

There are an infinite amount of problems and there is a finite amount of time I have to provide videos for solutions. I'm working diligently to keep adding new problems each week. Try using the advanced search function to help narrow down the search for the problem on the Video Search page...Advanced Video Search... and click on the button on the page to open up the advanced search. Not all items need to be selected, but the more done the more likely you will find your problem if it exists. If you still can't locate the problem, take a look at the similar problems and see if they help you. You can also send the problem to us to work on, but may not be done for a while.

The linking of problems to each textbook is provided by all people who use the site. My focus is on creating content on the site to get as many problems available for everyone to use to help them learn. Over time as more people start linking the problems to your textbook it will fill up over time. I do apologize that the site is not where I hope it will be one day, but everything takes time to reach the pinnacle of what I hope this site will be for each of you.

Studying some higher mathematics I would get stuck on a step that I couldn't understand why I was making a mistake or what was done. So my hope is that by showing all steps it will help people see the step that they are struggling with to improve their ability to solve problems. If you find the problems super easy you can increase the speed of the videos to 2x to shorter the length of the videos.

I'm currently not affliated with Abebooks.com. I have used their site and found it beneficial when locating textbooks to purchase. There is no obligation to use Abebooks.com and I receive nothing if you do use it. Please use any vendor you prefer to purchase a textbook.
