On the bright side, the problems which ARE correct have been tremendously helpful. Just as an answer guide should. The only reason it's earned two stars.
I should really give it one, because after all... this IS MATH and accuracy is of utmost importance!!!
How to solve square roots: √4 = 2 * 2 thus the √4 = 2
Now you try it! √-1
This approach makes it difficult to build any type of understanding for the basics when every question is at the extreme end of possibilities. I could understand if question 10 of 10 was extreme, but not the first questions in each sections. Additionally, this book uses completely non-standard labels for things which makes it even more confusing. Here's a made up example of how this can be confusing:
Pythagorean theorem: a^2 = c^2 + b^2
All in all, I found myself using this book only for the topics, then going elsewhere to actually learn about it and find examples. I found this is the only way to work with this book as the content and explanations are just garbage.
So if you do get this book, don't blindly believe everything it says. If you can't figure out how they got their answer it might be because they're wrong.
Needless to say, Cengage will be receiving an angry letter from me.
