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.

One-sentence 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.

Article: Look at the new belt in comparison to the old one to be sure they are the same width and have the same number of ribs going across the belt horizontally. The old belt may be slightly longer than the new one due to stretching. If the new belt is not the same width as the old one, it is the wrong belt. Make sure the new belt doesn't show any signs of damage from the factory or it may tear after you install it. Run the new belt through the pulleys in exactly the same way the old one was. Refer to the belt diagram in your vehicle's owner's manual or the picture you took of the belt before removing it to guide you. The belt should be long enough to route around all of the pulleys except the tensioner until you relieve the pressure on it. If the belt is loose after routing it, it is either the wrong size belt or you've routed it incorrectly. Use the same wrench to loosen the auto tensioner pulley, then pull the belt over it. Once the belt is in place, release the pressure on the tensioner so it holds the belt in place. It may be difficult to apply pressure to the tensioner and route the belt, so you may want to ask a friend to help. If your vehicle does not have an auto tensioner, insert a pry bar or piece of wood between the alternator and the engine. Run the belt over the alternator pulley, then use the bar to pry the alternator away from the engine and increase the tension on the belt. Tighten the bolts again as you apply tension. You may need help tightening the bolts as you apply pressure to the alternator. Be careful not to pry against anything plastic in your engine bay to avoid breaking anything.
Question: What is a summary of what this article is about?
Compare the new belt to the old one. Route the belt through the pulleys. Apply pressure on the auto tensioner and put the belt over it. Increase the tension on the belt.
