Problem: Write an article based on this summary: Align the numbers as an ordinary subtraction problem. Try some basic problems. Set up a more complicated problem. "Borrow" from the second digit. Solve the rightmost column. Finish the problem. Try a difficult problem. Check your answer.

Answer: Write the larger number above the smaller number. If the smaller number has fewer digits, line them up on the right, as you would in a decimal (base ten) subtraction problem. Some binary subtraction problems are no different than base ten subtraction. Line up the columns and, starting from the right, find the result for each digit. Here are a few easy examples: 1 - 0 = 1 11 - 10 = 1 1011 - 10 = 1001 You only need to know one special "rule" to complete any binary subtraction problem. This rule tells you how to "borrow" from the digit to the left so you can solve a "0 - 1" column. For the rest of this section, we'll set up a couple example problems and solve them using the borrow method. Here's the first: 110 - 101 =? Starting from the right column (the ones place), we need to solve the problem "0 - 1." In order to do this, we need to "borrow" from the digit to the left (the twos place). This has two steps to it: First, cross out the 1 and replace it with a 0, to get this: 1010 - 101 =? You've subtracted 10 from the first number, so you can add this "borrowed" number to the ones place: 101100 - 101 =? Now each column can be solved as usual. Here's how to solve the rightmost column (the ones place) in this problem: 101100 - 101 =? The rightmost column is now: 10 - 1 = 1. If you can't figure out how to reach this answer, here's how to convert the problem back to decimal: 102 = (1 x 2) + (0 x 1) = 210. (The sub numbers indicate which base the number is written in.) 12 = (1x1) = 110. Therefore, in decimal form this problem is 2 - 1 =?, so the answer is 1. The rest of the problem can now be solved easily. Solve it column by column, moving from right to left: 101100 - 101 = __1 = _01 = 001 = 1. Borrowing comes up a lot in binary multiplication, and sometimes you'll need to borrow multiple times just to solve one column. For example, here's how to solve 11000 - 111. We can't "borrow" from a 0, so we need to keep borrowing from the left until we turn it into something we can borrow from: 10110000 - 111 = 10111001000 - 111 = (remember, 10 - 1 = 1) 10111001100100 - 111 = Here it is written more tidily: 1011100 - 111 = Solve column by column: _ _ _ _ 1 = _ _ _ 0 1 = _ _ 0 0 1 = _ 0 0 0 1 = 1 0 0 0 1 There are three ways to check your answer. One quick way is to find a binary calculator online and plug in the problem. The other two methods are still useful, since you may need to check by hand on a test, and they will make you more familiar and comfortable with binary numbers: Add in binary to check your work. Add the answer together with the smaller number, and you should get the larger number. Using our last example (11000 - 111 = 10001), we get 10001 + 111 = 11000, which is the larger number we started with. Alternatively, convert each number from binary to decimal and see whether it is true. Using the same example (11000 - 111 = 10001), we can convert each number into decimal and get 24 - 7 = 17. This is a true statement, so our solution is correct.

Problem: Write an article based on this summary: Understand how scanning works. Turn on the product for which you want to program the remote. Point the remote at the product and hold the correct button. Wait for the remote's four lights to flash. Press the POWER button. Start pressing the remote's "Up" or "Down" arrow. Continue pressing the arrow until your product turns off. Press #. Press your remote's POWER button again.

Answer: Scanning allows you to manually run through all available codes for your selected product. While this is a good way to ensure that you'll eventually get the right code, it can also require you to scan through hundreds of codes before you find the correct one. For example, if you want to program the remote to work with your DVD player, make sure the DVD player is on. This button will depend on what you're trying to program the remote for: TV Press and hold the TV button at the top of the remote. Anything else Press and hold either the AUX button (all products) or the DVD button (DVD players and VCRs). These lights are at the top of the remote. Once you see them flash, you can release the button you're holding and proceed. It should be at the top of your remote. This will signify that your remote is now ready to begin scanning. This will start scanning through available codes. Each press of the arrow will test another code. When your product turns off, you've found the correct code. This will confirm the code and apply it to your remote. Your product should turn on, signifying that your remote is now programmed for the product.

Problem: Write an article based on this summary: Keep your genital area clean. Go to the bathroom as soon as you feel the urge. Go to the bathroom before and after sexual intercourse.

Answer:
Avoid using strong soap, cream, douches, powders and sprays. These products may increase the chances of contracting a UTI during pregnancy. Take a shower rather than a bath. If you must bathe, avoid taking more than two baths per day or bathing for more than half an hour at a time. Avoid bubble bath or bath beads, which can inflame the urethral opening. Make sure the tub is cleaned and rinsed well before taking a bath. Holding your urine keeps bacteria in your bladder longer and gives it a greater chance of developing into an infection. Take care to completely empty your bladder during each trip. Remember that the pressure of your growing uterus may complicate this practice; you'll need to carefully consider whether you're actually done urinating. Blot dry with toilet paper and do not rub your genital area. Wipe from front to back every time. Treat constipation properly as soon as possible. Wash your genital area with warm water before sex to eliminate bacteria. You may use a water-based lubricant during sex. You should not have sex if you are being treated for a urinary tract infection.
