Problem: Article: Because the pedals are always moving on a fixed gear, turning can feel very different than when riding freewheel bike. Don't take corners too tightly or your pedals may end up scraping against the ground or you might topple over. Slow down significantly when going around corners and take them wider than you normally would on a freewheel bike. Purchase bike safety gear at a bike store, department store, or online. A helmet will protect your head if you fall off of the bike. If you are just learning how to ride a bike, you should also consider wearing additional protective gear like knee pads, elbow pads, and a mouthguard. Make sure that the helmet fits snugly, but is not too tight on your head. Ensure that your bike has reflectors if you plan on riding it when it gets dark out. Many areas require you to have a front light and rear reflector while riding at night. Even if you have experience riding a freewheel bike, riding a fixed gear feels completely different. For that reason, you should practice riding it in an area that's free of obstacles until you're confident enough to ride it in other places.\ If you notice that the bike chain is drooping or loose, it could make it harder to ride the bike and could damage the chain. You can tighten the chain by unscrewing and repositioning the rear wheel further back. Check your bike chain periodically to make sure that it's tight. Professionals at the bike shop will also be able to replace or tighten your chain.
Summary: Take wider corners when turning. Wear a helmet and safety gear. Practice in an empty area when starting out. Keep the bike chain tight.

INPUT ARTICLE: Article: Wiping your tile with a dry cloth every other day will help minimize surface dirt. The more often you do routine cleanings, the less frequently you will need to do serious deep cleans with soap and water or cleaning solution. Creating a calendar reminder can help you remember to wipe your tile.. Whether it's a glass of wine or some salsa, food and drink are full of acids and natural juices, which can deteriorate granite tile. When something spills, clean it up right away with soap and water, drying your tile completely. This will keep any potential stains from setting. Bits of grout breaking off can scratch your granite and trap dirt and grime. Cleaning is a great time to get up close and personal with your tile, examining the integrity of each stone and grout line. Be sure to replace chipped or broken tiles and have your grout touched up wherever necessary. once a year. While sealant is no substitute for cleaning, it can make your granite more resistant to water damage and other spills. Seal your granite once a year with a high-quality granite sealant, such as Rock Doctor Granite Sealer or Stone Pro Granite Sealer, to keep your tiles in good condition.

SUMMARY: Establish a regular cleaning routine. Clean tiles as soon as something spills. Inspect grout and tiles for damage. Seal your granite

In one sentence, describe what the following article is about: 102 is 100. 103 is 1000. The powers 2 and 3 are the base-10 logarithms of 100 and 1000. In general, ab = c can be rewritten as logac = b. So, saying "ten to the power of two is 100" is equivalent to saying "the base-ten log of 100 is two." Each logarithmic table is only usable with a certain base (a in the equation above). By far the most common type of log table uses base-10 logs, also called the common logarithm. Multiply two numbers by adding their powers. For example: 102 * 103 = 105, or 100 * 1000 = 100,000. The natural log, represented by "ln", is the base-e log, where e is the constant 2.718. This is a useful number in many areas of math and physics. You can use natural log tables in the same way that you use common, or base-10, log tables. Let's say you want to find the base-10 log of 15 on a common log table. 15 lies between 10 (101) and 100 (102), so its logarithm will lie between 1 and 2, or be 1.something. 150 lies between 100 (102) and 1000 (103), so its logarithm will lie between 2 and 3, or be 2.something. The .something is called the mantissa; this is what you will find in the log table. What comes before the decimal point (1 in the first example, 2 in the second) is the characteristic. This column will show the first two or, for some large log tables, three digits of the number whose logarithm you're looking up. If you're looking up the log of 15.27 in a normal log table, go to the row marked 15. If you're looking up the log of 2.57, go to the row marked 25. Sometimes the numbers in this row will have a decimal point, so you'll look up 2.5 rather than 25. You can ignore this decimal point, as it won't affect your answer. Also ignore any decimal points in the number whose logarithm you're looking up, as the mantissa for the log of 1.527 is no different from that of the log of 152.7. This column will be the one marked with the next digit of the number whose logarithm you're looking up. For example, if you want to find the log of 15.27, your finger will be on the row marked 15. Slide your finger along that row to the right to find column 2. You will be pointing at the number 1818. Write this down. For 15.27, this number is 7. Your finger is currently on row 15 and column 2. Slide it over to row 15 and mean differences column 7. You will be pointing at the number 20. Write this down. For 15.27, you will get 1838. This is the mantissa of the logarithm of 15.27. Since 15 is between 10 and 100 (101 and 102), the log of 15 must be between 1 and 2, so 1.something, so the characteristic is 1. Combine the characteristic with the mantissa to get your final answer. Find that the log of 15.27 is 1.1838.
Summary:
Understand what a logarithm is. Identify the characteristic of the number whose log you want to find. Slide your finger down to the appropriate row on the table using the leftmost column. On the appropriate row, slide your finger over to the appropriate column. If your log table has a mean difference table, slide your finger over to the column in that table marked with the next digit of the number you're looking up. Add the numbers found in the two preceding steps together. Add the characteristic.
