Review title: Don't waste your money on this Product review: I thought I was getting a powerful window fan. For the price of this fan I could have gotten about 5 larger box fans from any major outlet store. It is not as powerful as my cheaper $18.00 box fan.

Review title: Sneakers Product review: I tried machine washing my athletic shoes but I soon found them looking dirty again. I got an idea to spray Scotchgard on my sneakers and they stayed clean looking longer. If I got dirt on my sneakers I just wiped them off with a damp cloth. I'm going to do my tote bags next. Thanks for a great product.

Review title: Cheating on readers Product review: 1. Many lines are direclty copied from "trading global currency market".2. Did not proof read. There are many typos, so confusing.3. Does not explain details when they are needed.4. Lacks explanations for figures. Figures spread all over the book, somewhere I think they don't match text.This guy, Luca, seems to be famous. He is maybe good at trading himself and he is able to write a good book, but he just did not put himself into it.

Review title: Not as good as others in this series Product review: I was pretty disappointed in this book. It seemed as if Ms. Hamilton was required to write a book for her publisher, so she simply shot this one out. It wasn't very inspired or interesting. I actually finished the book in two evenings reads (and I work full time and have an infant...so I don't stay up that late). I hope her next installment gives me bit more storyline.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
