Title: good, bit difficult
Review: The book was a bit harder than i thought, however a little extra challenge is never too bad. Has some proofs, some logic problem solving. The reason i rated this 4 is because of where everything is placed in the book. After you solve the problem, u have to go to another page to see the answer, or if you dont enderstand the problem, u have to dig in the book to see where its solution is.
