This book is about algebra. This is a very old science and its gems have lost their charm for us through everyday use. We have tried in this book to refresh them for you. The main part of the book is made up of problems. The best way to deal with them is: Solve the problem by yourself - compare your solution with the solution in the book (if it exists) - go to the next problem. However, if you have difficulties solving a problem (and some of them are quite difficult), you may read the hint or start to read the solution. If there is no solution in the book for some problem, you may skip it (it is not heavily used in the sequel) and return to it later. The book is divided into sections devoted to different topics. Some of them are very short, others are rather long. Of course, you know arithmetic pretty well. However, we shall go through it once more, starting with easy things. 2 Exchange of terms in addition Let's add 3 and 5: 3+5=8. And now change the order: 5+3=8. We get the same result. Adding three apples to five apples is the same as adding five apples to three - apples do not disappear and we get eight of them in both cases. 3 Exchange of terms in multiplication Multiplication has a similar property. But let us first agree on notation.

This book contains an extensive collection of exercises and problems that address relevant topics in linear algebra. Topics that the author finds missing or inadequately covered in most existing books are also included. The exercises will be both interesting and helpful to an average student. Some are fairly routine calculations, while others require serious thought.The format of the questions makes them suitable for teachers to use in quizzes and assigned homework. Some of the problems may provide excellent topics for presentation and discussions. Furthermore, answers are given for all odd-numbered exercises which will be extremely useful for self-directed learners. In each chapter, there is a short background section which includes important definitions and statements of theorems to provide context for the following exercises and problems.

One night, when Ethan reaches under his bed for a toy truck, he finds this note instead: "Monsters! Meet here for final test." Ethan is sure his parents are trying to trick him into staying under the covers, until he sees five colorful sets of eyes blinking at him from beneath the bed. Soon, a colorful parade of quirky, squeaky little monsters compete to become Ethan's monster. But only the little green monster, Gabe, has the perfect blend of stomach-rumbling and snorting needed to get Ethan into bed and keep him there so he falls asleep—which as everyone knows, is the real reason for monsters under beds. With its perfect balance of giggles and shivers, this silly-spooky prequel to the award-winning I Need My Monster and Hey, That's MY Monster! will keep young readers entertained.

Brad Thor's Summer 2018 Fiction Pick for THE TODAY SHOW! NAMED A BEST BOOK OF THE YEAR BY Elle • Refinery29 • PopSugar • Verge Author of LA Times Prize finalist The Cartographers “The Book of M is devastating and inventive as Shepherd examines the value of memory, packing in imaginative twists as she goes.” —USA Today "Eerie, dark, and compelling, [The Book of M] will not disappoint lovers of The Passage and Station Eleven." —Booklist WHAT WOULD YOU GIVE UP TO REMEMBER? Set in a dangerous near future world, The Book of M tells the captivating story of a group of ordinary people caught in an extraordinary catastrophe who risk everything to save the ones they love. It is a sweeping debut that illuminates the power that memories have not only on the heart, but on the world itself. One afternoon at an outdoor market in India, a man’s shadow disappears—an occurrence science cannot explain. He is only the first. The phenomenon spreads like a plague, and while those afflicted gain a strange new power, it comes at a horrible price: the loss of all their memories. Ory and his wife Max have escaped the Forgetting so far by hiding in an abandoned hotel deep in the woods. Their new life feels almost normal, until one day Max’s shadow disappears too. Knowing that the more she forgets, the more dangerous she will become to Ory, Max runs away. But Ory refuses to give up the time they have left together. Desperate to find Max before her memory disappears completely, he follows her trail across a perilous, unrecognizable world, braving the threat of roaming bandits, the call to a new war being waged on the ruins of the capital, and the rise of a sinister cult that worships the shadowless. As they journey, each searches for answers: for Ory, about love, about survival, about hope; and for Max, about a new force growing in the south that may hold the cure. Like The Passage and Station Eleven, this haunting, thought-provoking, and beautiful novel explores fundamental questions of memory, connection, and what it means to be human in a world turned upside down.
