The Pythagorean theorem seems to have been selected for introduction in chapter one as it illustrates the contribution of historical mathematicians, the fact that people from many countries worked on this, and the fact that theorems are important. The topic appears briefly in a few other places in the book. The book returns to the major topic in chapter 9 of 13, which is the quadratics chapter. Here, the product property of radicals is introduced as it seems a convenient place. The only material on simplification is given with the product property.
Problems are mostly easy with a few medium problems related to the product property.
The quotient property is not addressed. The distance formula is covered with modest problem count, nearly all easy. The efficacy for this major topic is a disaster. The material is largely missing, and the little that is included is scattered in a way that isn't helpful to learning. This text does not support even modest student learning for this major topic.
