INPUT ARTICLE: Article: This method does not use powers. As such, it is simpler for converting large numbers in your head because you only need to keep track of a subtotal. The first thing you need to do is to write down the binary number you'll be converting using the doubling method. Let's say the number you're working with is 10110012. Write it down. Since you're working with the binary number 10110012, your first digit all the way on the left is 1. Your previous total is 0 since you haven't started yet. You'll have to double the previous total, 0, and add 1, the current digit. 0 x 2 + 1 = 1, so your new current total is 1. Your current total is now 1 and the new current digit is 0. So, double 1 and add 0. 1 x 2 + 0 = 2. Your new current total is 2. Just keep going. Next, double your current total, and add 1, your next digit. 2 x 2 + 1 = 5. Your current total is now 5. Next, double your current total, 5, and add the next digit, 1. 5 x 2 + 1 = 11. Your new total is 11. Double your current total, 11, and add the next digit, 0. 2 x 11 + 0 = 22. Now, double your current total, 22, and add 0, the next digit. 22 x 2 + 0 = 44. Now, you're down to your last number and are almost done! All you have to do is take your current total, 44, and double it along with adding 1, the last digit. 2 x 44 + 1 = 89. You're all done! You've converted 100110112 to decimal notation to its decimal form, 89. Write your final answer as 8910 to show that you're working with a decimal, which has a base of 10. Doubling is used because the given number is of base 2.  If the given number is of a different base, replace the 2 in the method with the base of the given number.  For example, if the given number is in base 37, you would replace the "x 2" with "x 37".  The final result will always be in decimal (base 10).

SUMMARY: Write down the binary number. Starting from the left, double your previous total and add the current digit. Double your current total and add the next leftmost digit. Repeat the previous step. Repeat the previous step again. Repeat the previous step again. Repeat the previous step again. Continue doubling your current total and adding the next digit until you've run out of digits. Write the answer along with its base subscript. Use this method to convert from any base to decimal.

In one sentence, describe what the following article is about: To arrange the setup for drying the pretzels, line a baking sheet with foil, wax paper, or parchment paper. Next, place a wire cooling rack on top of it so the baking sheet will catch any yogurt that drips off. Lining the baking sheet makes it easier to clean after all of the pretzels have set. None of the yogurt will actually make it to the baking sheet, and you can just throw the liner away. Add 2 cups (250 g) of powdered sugar , ⅓ cup (85 g) plain low fat yogurt, and 1 teaspoon (7 g) of seedless blackberry preserves to a medium size bowl. Mix the ingredients with a whisk until they are fully combined.  It’s best to use plain, unsweetened yogurt so the coating isn’t overly sweet. You can substitute your favorite flavor of preserves for the blackberry. Use a seedless variety, though, and strain out any large pieces of fruit or skin before mixing it into the coating. When you’ve finished mixing up the yogurt coating, dip 36 thin pretzel twists in one at a time. Use a spoon or wooden skewer to turn them over in the coating so both sides are coated and then lift them out onto the wire cooling rack. Repeat the process with all of the pretzels. If you have a pair of tongs, you can use them to dip the pretzels into the yogurt coating. If you are making the pretzels for a gift or special occasion, you may want to garnish them. While the coating is still soft, add a light layer of colored sprinkles to the pretzels.  Adding the sprinkles is optional. You can leave the pretzels plain if desired. You can substitute colored sugar for the sprinkles if you prefer. After you’ve added the sprinkles, leave the pretzels to dry on the rack for 3 to 4 hours. For the best results, serve the pretzels immediately. Store any leftover pretzels in an airtight container, but try to eat them within a day of making them.
Summary: Set a wire cooling rack on a lined baking sheet. Combine the powdered sugar, yogurt, and preserves. Dip the pretzels in the yogurt mixture and set on the cooling rack. Add sprinkles to the pretzels if desired. Let the yogurt coating harden for several hours before serving.

INPUT ARTICLE: Article: Baking soda makes a great natural stain remover. It's gentle enough to use on almost any type of fabric. Mix a tablespoon of baking soda with enough water to make a thick paste. Alternatively, mix the baking soda with hydrogen peroxide or white vinegar.  Baking soda paste is best used on fabrics that don't require dry cleaning. You'll have to rinse it away when you're finished, so the clothes will get wet. Baking soda paste works well to remove stains caused by oil, grease, dirt, food, and many other substances. Lightly rub it into the stain. Make sure it covers the entire stained area, overlapping the edges. Allow it to sit on the stain for 15 minutes.  If the stain is on sturdy clothing, you can scrub it using an old toothbrush. Scrub the baking soda into the stain to make sure it can treat all of the fibers. This method is fine to use on denim and thick cotton. Don't scrub the baking soda into delicate fabric. Silk, satin and other thin fabrics could warp when scrubbed. Run it under warm running water to rinse away the baking soda along with the stain. For more delicate fabrics, you can wipe away the baking soda using a dampened cloth. Some difficult stains require more than one treatment. Apply a second round of paste to the stain. Let it sit for 15 minutes, then rinse it away. If the stain remains, you may need to use a chemical stain remover or take the item to be professionally cleaned.

SUMMARY:
Make a baking soda paste. Apply the paste to the stain. Rinse away the baking soda. Repeat the treatment if necessary.
