Article: Most landlines have the option to call internationally already enabled. However, you should talk to your phone provider to figure out how much it will cost you to call. They may be able to set you up with a plan to reduce the cost of the call. Plus, they can turn your international calling on it if it isn't set up already. With a landline, you just dial the number normally with the exit code and country code in front. If you find your phone provider's international calling is too expensive, you can purchase an international calling card. With these, you buy a card that has a certain number of minutes on it. Dial the (toll-free) number for the calling card first, then put in a pin number. After that, you can dial your international number. The call will be charged to the calling card instead of your provider. You can find calling cards at big box stores, pharmacies, gas stations, and online. You may need to enable your international plan before making the call; you can check your plan online or call your service provider to enable it. Then, you can dial the number as you would from a landline, putting in the exit code and the country code first. Always check how much a call will be, as you don't want to be surprised by a huge bill! VoIP or "Voice over Internet Protocol" refers to making calls using the internet. Some VoIP systems require that both ends of the call be on the internet, which is usually free, depending on the service you use. However, you can also use VoIP to call actual phone numbers. Though it may cost a little to call an actual number, it's usually cheaper than traditional plans. All you need to do is find a service on your computer or phone, add credits if it requires it, and put in your number using the country codes. For instance, try Skype or Google Voice. Both of these charge for making calls internationally, but the fees are cheaper than other plans.
Question: What is a summary of what this article is about?
Use your landline to call internationally. Purchase a calling card to avoid using your phone's calling plan. Call using your mobile phone for an easy option. Try a VoIP call for a cheap option.
Article: Recognize that addition and subtraction are really the same process. Subtraction is nothing more than adding a negative number. Therefore, addition and subtraction are treated as versions of the same process. To add two or more complex numbers, first just add the real portions of the numbers together.  For example, to simplify the sum of (a+bi) and (c+di), first identify that a and c are the real number portions, and add them together. Symbolically, this will be (a+c). Using actual numbers instead of variables, consider the example of (3+3i) + (5-2i). The real portion of the first number is 3, and the real portion of the second complex number is 5. Add these together to get 3+5=8. The real portion of the simplified complex number will be 8. In a separate operation, identify the imaginary portions of each complex number and add them together.  For the algebraic example of (a+bi) plus (c+di), the imaginary portions are b and d. Adding these together algebraically gives the result (b+d)i. Using the numerical example of (3+3i) + (5-2i), the imaginary portions of the two complex numbers are 3i and -2i. Adding these gives the result of 1i, which can also be written just as i. To find the final simplified version of the sum, put the real part and the imaginary part back together. The result is the simplified sum of the complex numbers.  The sum of (a+bi) and (c+di) is written as (a+c) + (b+d)i. Applying the numerical example, the sum of (3+3i) + (5-2i) is 8+i.
Question: What is a summary of what this article is about?
Add the real portions together. Add the imaginary portions together. Combine the two parts to form the simplified answer.
Article: If you choose a title that sounds like it belongs in one genre while the actual content of the story belongs in another, you’ll not only confuse potential readers, you may alienate them. For example, if your title sounds distinctly fantasy-esque, like “The Dragon of the Old Tower,” but the story is in fact about modern-day brokers on Wall Street, you’ll alienate those who pick up your story looking for fantasy and you’ll miss entirely those looking for a story about something modern or about the world of elite finance, etc. In the majority of cases, titles that are brief but impactful are more successful than those that are long and difficult to remember. For example, “A Man Discovers the Perils of a Solo Trek Through the Yukon” is likely less compelling to potential readers than “To Build a Fire,” which is shorter and more imaginative. Titles that use poetic language, vivid imagery, or a bit of mystery tend to be alluring to potential readers.  Poetic language in a title, like “A Rose for Emily” or Gone with the Wind, draws readers with an elegant turn of phrase that promises an equally poetic story or writing style. Titles that evoke vivid imagery appeal to readers because they conjure something tangible and meaningful. A title like Midnight in the Garden of Good and Evil, though long, creates an immediate and vivid image that conjures an idea of a battle between good and evil.  Imbuing your title with a bit of mystery can also draw readers in. A title like Something Wicked This Way Comes (also an allusion from Macbeth) or “The Black Cat” give just enough information to raise questions that will pull the reader into the story. Though alliteration--the repetition of successive sounds at the beginning of words--can make a title catchier or more memorable, it can also make it sound trite or hokey if not done well.  Subtle alliteration, like I Capture the Castle or The Count of Monte Cristo, can add appeal to a title. Obvious or forced alliteration, on the other hand--like "The Guileless Guide of Gullible Gus" or "The Especially Exciting Endeavors of Elanor Ellis"--can easily dissuade a potential reader from picking up your story.
Question: What is a summary of what this article is about?
Create a genre-appropriate title. Limit the length. Make it interesting. Use alliteration sparingly and with caution.
