INPUT ARTICLE: Article: Sometimes numbers are written out, making conversion to standard form tricky. In this case, convert the number to numerical form first. Large numbers have multiple sections. Write each one out in numerical form first.  If a number is spelled out as six hundred and thirty-seven thousand, four hundred ninety-two, start at the left. The first part is six hundred and thirty-seven thousand. Write this as 637,000. The second part is four hundred, so write 400. The final part is ninety-two, so write 92. You can do the same with small numbers as well. Very small numbers are common in measurements, like "one-thousandth of an inch." The thousands place value is 4 spaces to the right of the decimal point. So in written form, this is 0.0001. Another way to convert small numbers is to imagine them as fractions. "One-thousandth of an inch" is equal to 1/1,000. Divide 1 by 1,000 and get 0.0001. Once you’ve expressed the different parts of the written number in numerical form, finding the numerical form for the entire number is easy. Set up an equation and add together all the parts of the number. The sum is the written number expressed in numerical form.  For our example, your equation is 637,000 + 400 + 92. The result of the equation is 637,492. If you're in the US, remember to add a comma after every 3 digits starting from the left to keep track of the number. If you end up with 545600, for example, make it 545,600. Outside the US, use decimal points instead of commas. So 545,600 should be 545.600. Once you express the number in numerical form, then expressing it in standard form is much easier. Simply go through the same process as you would for any other number to find its standard form.  For 637,000, going through the process gives you 6.37 x 105. Do the same with small numbers as well. If one-thousandth of an inch is 0.0001, then convert it to standard form by going through the process to write small numbers. The result is 1 x 10-4.

SUMMARY: Convert each individual part of the number to numerical form. Add up the different parts of the number. Go through the process to place that number in standard form.


INPUT ARTICLE: Article: Studies have shown that physical activity can improve mental alertness and cognitive function. Your brain works better and you can think more clearly after exercising.  Physical activity also helps boost memory and recall, which is important when studying. Aerobic exercise helps pump blood to your brain, which helps give it oxygen and nutrients that it needs to work and process information. Exercise has many benefits, but one important benefit for students is that exercise helps boost your mood. Regular exercise helps reduce anxiety, which you may feel because of your studies.  Regular aerobic exercise has been found to help reduce tension, stabilize your mood, and reduce stress. Just five minutes of cardio can help start to reduce anxiety. Exercise provides multiple benefits that help improve your energy. This is important if you are a student trying to study for multiple exams or classes. Doing some aerobic exercise may be more effective than hitting the coffee shop.  Regular exercise boosts energy levels. Since exercise reduces stress, it helps reduce fatigue associated with elevated stress levels. Exercise boosts your ability to sleep. Adequate rest helps you feel more alert and allows your brain to function better as you study.

SUMMARY: Know that exercise boosts mental function. Exercise to reduce stress. Incorporate exercise to improve energy.


INPUT ARTICLE: Article: If you’ve been exposed to birds that may have been infected with bird flu, monitor closely for any signs of illness.  These may include fever and cough, serious respiratory distress and discomfort in your chest, difficulty breathing, abdominal pain, and diarrhea. Quick diagnosis and medical treatment are vital, as certain types of avian flu may lead to pneumonia, respiratory failure, mental disarray, seizures, organ failure, and death. Regardless of the type of flu you’ve caught, do everything you can to help prevent the infection from spreading.   For instance, cover your mouth and nose and turn away from others when you cough or sneeze.  Dispose of soiled tissues immediately, and wash your hand with warm water and soap.  Avoid areas or places with lots of people. Avoid kissing, hugging, or sharing any dishware with others. If you are concerned that you may have avian flu, see your doctor right away.  Notify the first medical professional or receptionist you see of your concerns. They will seat you away from others and give you a surgical mask to cover your nose and mouth.   If you are diagnosed with avian flu, your doctor will automatically notify the CDC, which will provide them with the latest guidance about how to help prevent the flu from spreading. The CDC will also notify other agencies and the World Health Organization about some cases of bird flu, such as H5N1. Talk to your doctor about taking influenza antiviral drugs to prevent infection. While these drugs are more commonly used to treat different types of flus, they can potentially keep from falling ill.  There is a specific vaccine for H5NI, a particularly dangerous type of bird flu.  However, it is unlikely this vaccine will be used unless there is a substantial breakout of this virus.  The standard flu vaccine will not prevent an infection from bird flu.

SUMMARY: Watch closely for signs of illness. Take extreme precaution if you have flu symptoms. Seek medical assistance. Consider taking antiviral drugs.

Type in about:config and then tap Search or ⏎ Return in the keyboard. If there's any text in the search bar, remove it before typing in about:config. You'll find this below the search bar at the top of the screen. Type in dom.disable_open_during_load and wait for the dom.disable_open_during_load option to appear. Tap the dom.disable_open_during_load section to expand it. You should see the pop-up blocker's status (which should be "true") listed on the left side of the screen. If the status says "false" instead, your Firefox browser is already blocking pop-ups. It's in the bottom-right corner of the pop-up blocker's section. Doing so will change the pop-up blocker's status from "true" to "false", signifying that the pop-up blocker is enabled. Even with the pop-up blocker enabled, not all pop-ups will be blocked.
