<p>Can someone PLEASE explain what tip 3 is supposed to be teaching? I mostly get confused by the 3rd scenario which is explained in example 2. , but I really don't understand the explanation at all....</p>
<p>It's on page 16 and it regards combined range of two intervals when one interval is subtracted from another.</p>
<p>i know how to do the practice problems… but the examples and explanations seriously threw me off…</p>
<p>ok jk i got it…</p>
<p>the explanation was truly horrible… at least for my thought process…</p>
<p>Why do you think I call it Dr Junk’s book! On a serious note, it is one of the worst choices to prepare for the SAT Reasoning test. It’s a poorly edited book that has little to no relevance to the real test. Safe and except that it covers math concepts.</p>
<p>Do youself a favor and throw it away. That or give it to a classmate you really do not like! </p>
<p>I don’t have the book but I found a pdf containing some “tips,” supposedly from Dr. Chung (tip 3 is the same one you were mentioning). Honestly you are just better off just finding the maximum and minimum values of x-y using a greedy algorithm. Also on the pdf were some sample problems that were poorly worded or had multiple correct answers. I’m sure many of us here can write a better test preparation book than some of the ones out there.</p>
