This book is the solution to all your math problems. It has easy-to-follow explanations of all sorts of equations. If you still think this is too complicated, just ask your math teacher or tutor for help! __Note:__ this post is not written by Sebastian Lazo. Este libro es la solución a todos sus problemas de matemáticas. Tiene explicaciones fáciles de entender para todos y cada uno de los tipos de ecuaciones. Si aún no está convencido que es demasiado complicado, solo pida ayuda a su profesor o tutor para resolver los problemas. O . The book is really easy to understand and the author expresses everything in a very good way to build each chapter. The faults that I can see are that it's just 30 chapters long and there are only 2 lessons per section. This means that there are only six lessons per book, which is quite short. The book does not explain how to solve the problems, but you will find solutions at the end of each section. For example, in this section : "15". This is because it's using our own knowledge. If we subtract the two numbers we will get 9 which is smaller than 10 so we know that "15" can be negative or zero. The word "more than" refers to the absolute values so it cannot be 15 to 0. That's why the answer is 9. This makes sense because 15 minus 0 equals 15 and dividing by 2 gives us 9 not 10. I recommend this book because it is easy and understandable and it has a lot of practice problems. If you want to, go ahead and buy this book! The book is very good for beginners, but if you're willing to do all the exercises then I can't recommend this book. You really need to practice a lot on math.https://www.amazon. es/dp/5823289040 40 https://www.amazon.es/dp/B00QHRBZHU https://www.amazon.es/dp/B00QHRBZHU https://www.amazon.es/dp/5823289040 www.ebay. 8eeb4e9f32 15
