Отрывок из книги
One-thousand-one algebra problems: You must wonder what inspired such an endeavor.
One possibility for the inspiration is 1,001 Arabian Nights. (Okay, I’m really stretching here, but why not?) 1,001 Arabian Nights is a collection of stories and folk tales, compiled over several centuries. Likewise, 1,001 Algebra II Practice Problems For Dummies is a collection of math problems and explanations, and some of them involve interesting stories. This book wasn’t compiled over centuries (though my editors say it seemed to take that long), but the concepts and ideas involved took mathematicians centuries to develop.
