INPUT ARTICLE: Article: Craigslist allows you to post advertisements based on where you live. First, choose your country, then state, then city from the options that are listed on the website. If your exact city is not listed as one of the options, choose the city that is closest to you. " Navigate to the classifieds section by clicking the "create a posting" link located in the top left corner of the webpage. Select "for sale by owner," then click "cars & trucks-by owner" to indicate that you are a private seller. This gives potential buyers an accurate idea of who they are buying a car from. Examine the list of neighborhoods in your city to see which most accurately describes your current location. Because some cities are quite large, the neighborhood listing gives potential sellers a more refined idea about where they might need to travel to locate the item. Alternatively, you can visit the Craigslist forums and follow the onscreen instructions at the top right to request a new Craigslist area. Fill in the title box with the car's year, followed by the make, and then the model. The title for the car ad must always list these items in this exact order. Always list the car's year in a four-digit format. A sample title for your car ad could read "2007 Toyota Prius" or "2010 Chevrolet Impala." Follow the online prompts to list your pre-determined car price, where the vehicle is currently located, and other technical specifications about the car that a potential buyer would need to consider before making a purchase. You will need to list crucial technical information about your car such as the odometer reading, the kind of fuel it runs on, the kind of transmission it has, and whether it has 4, 6, or 8 cylinders. List either a phone number or email address where you can be reached. Consider setting up an email address to use exclusively for your craigslist ad. Take well-lit photos that accurately represent your car's appearance so that buyers have a good idea of what your car looks like. Ads without photos are typically confused for spam. Clean your car then take photos that show the car from different angles, such as the front, rear, both sides, and the interior. Don't purposely obscure any scratches or damage your car may have from the photos. The seller will find out eventually, so you might as well be upfront to save everyone's time and effort! Examine the preview of your ad carefully before posting it. The preview will show you exactly how it will look to potential buyers, so make sure to spot any potential errors. If you want to change something and continue editing your ad, select the "Edit" button. Otherwise, click the "Continue" button to continue the process and post your ad. " Read and accept the "Terms of Use" to familiarize yourself with Craigslist's regulations. Follow the prompts to confirm your email address, then click "publish" to officially post your ad.

In one sentence, describe what the following article is about: While some students can find story problems more complex, others will thrive when they better understand the real-world implications of learning addition. Help your child recognize three different situations that require addition: "Result unknown" problems -- for example, if Meredith has two cars and on her birthday she receives three more, how many cars does she now have in all? "Change unknown" problems -- for example, if Meredith has two cars, and after opening all her birthday presents she now has five cars, how many cars did she receive for her birthday? "Start unknown" problems -- for example, if Meredith receives three cars for her birthday and now she has five, how many cars did she have to start off with? Real-world situations will involve different parameters. Understanding how these work will help your child develop tools to solve addition story problems. "Join" problems involve the growth of a quantity. For example, if Elizabeth bakes three cakes and Sara bakes six more, how many cakes are there altogether? "Join" problems may also ask students to solve for unknown change or start figures -- for example, if Elizabeth bakes three cakes and Elizabeth and Sara produce nine cakes in all, how many cakes did Sara bake? "Part-part-whole" problems involve adding two static figures. For example, if there are 12 girls in the class and 10 boys, how many students are in the class altogether? "Compare" problems" involve an unknown in a compared set of values. For example, if Geoff has seven cookies, and he has three more cookies than Laura, how many cookies does Laura have? Reading- and writing-oriented children may especially benefit from books that incorporate addition themes. Conduct a Web search for "teaching addition with books" to access lists of useful volumes compiled by educators.
Summary: Practice different types of story problems. Teach children to recognize "join," "part-part-whole," and "compare" problems. Utilize books that teach addition concepts.

INPUT ARTICLE: Article: Avoid shelving books too tightly or leaning against one another as this can cause lasting warping, structural damage, and cracking. When shelving, place books of similar height and length next to one another to avoid stressing the spine. Placing a book flat is an alternative to upright shelving. However, when shelving a book horizontally be sure to put as little weight on top of it as possible. Grab the middle of the spine when removing a book from a shelf to avoid damaging the head (top) and foot (bottom) of the spine. Place your books in a controlled climate to help prolong the book's quality. Sunlight, heat, and humidity can all have negative effects on the book's binding, structure, and page quality. Humidity can cause mildew to grow on your books. If you live in a particularly humid environment, and mildew begins to grow, simply wipe the mildew with a very dry cloth and leave the book in sunlight for 30-45 minutes. Be careful not to leave it longer as sunlight can cause the cover to fade. If a rare or fragile book grows mildew bring it to a specialist in book conservation. Clean your books regularly in order to prevent natural wear and tear and increase the quality of their storage. Dusting your books will help reduce permanent page and cover aging. Make sure to dust your books from the spine outward so dust does not settle behind the spine. Avoid storing books in plastic bags. Books need to breathe and plastic can cause molding or warping. Instead, try wrapping the book in acid-free cloth or purchases a book storage box.

SUMMARY:
Shelve books upright. Keep books out of direct sunlight and in a cool area. Keep your books clean.
