article: Hold the toothbrush from the handle grip with your thumb. Run the bristles back and forth repeatedly under the hot water. Do this every time, before and after, you brush your teeth and make sure it has been completely cleaned. After finishing a cleaning session you need to shake out the bristles, and make sure the moisture is gone. Tap the brush handle against a hard surface, such as the sink, to get some of the water out of the bristles. You can also shake the brush briskly over the sink, bristles face down, to get more moisture out, but never let the brush touch the sink. Let the brush finish drying without the bristles coming into contact with any other surface. If the bristles touch any other surface, then you might want to re-run them under hot water, and start the drying process over. Use an alcohol-based rinse or even chlorhexidine 0.02% mouthwash for this. Pour some of the rinse into a clean plastic cup. Just pour enough to dip the toothbrush head and bristles in. Grasp the toothbrush by the handle grip and dip the bristles into the rinse. Swish the bristles around in the rinse for 30 seconds. Remove the brush, tap the handle on a hard edge (such as the sink) to shake out any moisture, and then store it upright to dry without the bristles coming into contact with other surfaces or other bristles of someone else's toothbrush. Dispose of the cup. Never dip the brush into the main bottle of rinse, or you risk cross-contaminating the entire bottle as well as the brush. Extend this rinse to a 10 minute soak if you are sick. Many sanitizers use ultraviolet (UV) light to kill the bacteria on the bristles of the toothbrush. The basic technique is the same for most of these devices. Open a user accessible casing of the device. Insert the toothbrush or toothbrush head (in the case of electric brushes) into an internal compartment. Close the casing. Turn on the device and let the UV light clean the bristles for the instructed periodusually just a few minutes. Remove the brush when the device signals you to do so. There are some alternative methods to these automatic sanitizers that use steam or soundwaves instead of UV light. The steps to use them will be mostly the same, but the duration of the cleaning may differ. Also, the sanitizers using steam have almost the same rate of eliminating bacteria similar to the UV ones. Sometimes the best policy is to simply get a new toothbrush. The American Dental Association recommends replacing your brush every 3-4 months. However, closer examination of the bristles can tell you if replacement needs to happen sooner. Look for the bristles to be individually fraying (splitting at the ends). Also if you see whole sets of the bristles bent in one direction without returning to an upright position even after drying, then it is time for a new brush. Some toothbrushes have some colored bristles on them, which indicates when to change the toothbrush. As the color starts to fade and becomes almost the same as the other bristles, it is time to get a new toothbrush.

Write an article based on this "Define your formula for consecutive integers. Set up a formula to calculate only even integers. Define a formula to find the sum of odd integers. Work any of your defined formulas to find the sum."
article: Once you've defined n{\displaystyle n} as the largest integer you're adding, plug the number into the formula to sum consecutive integers: sum = n{\displaystyle n}(n{\displaystyle n}+1)/2. For example, if you're summing the first 100 integers, plug 100 into n{\displaystyle n} to get 100(100+1)/2. If you're finding the first 20 integers, use 20 for n{\displaystyle n}. Work 20(20+1)/2 to get 420/2. Your answer will be 210. If the problems asks you to find the sum of only the even integers in a sequence starting with 1, you'll need to use a different formula. Plug your highest integer into n{\displaystyle n} so: sum = n{\displaystyle n}(n{\displaystyle n}+2)/4. For example, if the problem asks you to find the sum of even integers from 1 to 20, use 20 as n{\displaystyle n}. Your formula will be 2022/4. If the problems asks you to find the sum of only the odd integers, you'll need to find n{\displaystyle n} first. To find n{\displaystyle n}, add 1 to the highest number of the sequence. Then use it in this formula: sum = (n{\displaystyle n}+1)(n{\displaystyle n}+1)/4. For example, to add the odd integers from 1 to 9, add 1 to 9. The equation will now look like 10(10)/4. Once you've worked the equation, you'll get 10(10)/4 to equal 25. Once you've plugged in the integer, multiply the integer by itself plus 1, 2 , or 4 depending on your formula. Then divide your result by 2 or 4 to get the answer. For the example of consecutive formula 100101/2, multiply 100 by 101 to get 10100. Divide this by 2 to get an answer of 5050. For the example of even integers 2022/4, multiply 20 by 22 to get 440. Divide this by 4 to get a result of 110.

You'll need a confirmation of enrollment in order to apply for a student visa. Once you've enrolled at a university, they'll send you a written confirmation, which you'll include in your visa application. If English isn't your first language, you'll need to show proof of your English proficiency. Acceptable tests include the International English Language Testing System and the TOEFL paper or internet tests. The minimum score for the International English Language Testing System is 5.5. The minimum score for the TOEFL paper-based test is 527. For the TOEFL internet-based test, the minimum score is 46. The financial capacity requirement is a unique hoop you'll need to jump through in order to obtain a student visa. You'll need to provide documents that prove you can support yourself for 12 months or, for shorter courses, the duration of your stay. Example documents include bank statements, income statements, university financial aid statements, tax returns, and credit history.

Student loans and scholarships count, so include any financial aid you've been awarded. If your parents are helping you pay for your education, provide information about their income. Provide as much documentation as possible in your visa application. The more evidence you provide, the better your chances of obtaining a visa.
