In one sentence, describe what the following article is about: Doing so places your cursor in the cell. Type =AVERAGE( ) into the cell. You can press the left arrow key once to do this, or you can click in between the two parentheses in the text box at the top of the document. You can input a range of data cells by typing the name of the first cell in the list of data, typing a colon, and typing in the last cell name in the column. For example, if your list of numbers goes from cell A1 through cell A11, you would type in A1:A11 in between the parentheses.  Your completed formula should look something like this: =AVERAGE(A1:A11)  If you want to calculate the mean of a few numbers (not a whole range), you can type each number's cell name between the parentheses and separate the names with commas. For example, to find the mean of A1, A3, and A10, you would type in =AVERAGE(A1,A3,A10). Doing so will run your formula, causing the mean of your selected values to display in your currently selected cell.
Summary: Click an empty cell. Enter the "mean" formula. Place your cursor in between the parentheses. Add your data range. Press ↵ Enter.

In one sentence, describe what the following article is about: Sometimes exposure to cold temperatures can reduce swelling in your finger enough to allow a ring to slip off. Fill a bowl with cold water and soak your hand in it for a few minutes, then try to remove the ring. The water should be nice and cold, but not icy. If your tap water is not cold enough, put some water in your refrigerator to chill it. In many cases, a tight ring will slip off with the help of a little lubricant. If your finger is not extremely swollen, try rubbing a gentle lubricant, such as hand lotion, petroleum jelly, soap, or baby oil on your finger around the ring. Once your finger is well lubricated, try to slide the ring off.  If your skin is broken, use an antibiotic ointment or vitamin A and D ointment. The lubrication method may work best in combination with other methods. Try cooling your finger in cold water to reduce swelling before lubricating it. This method works by compressing your finger, making it easier to slide the ring off. Start by taking a length of thread, string, or dental floss, and slipping one end of it under your ring. You may need to use a needle (carefully!) to pull the string between the ring and your finger. Once the end of the string is in place under your ring band, start winding the string around your finger just above the top of the ring. Continue until your finger is wrapped to just past the knuckle. Pull up on the end of the string that is sticking out from under your ring. This should cause the string to unwind and push the ring up over your knuckle. Relax your hand and allow your knuckle to bend slightly as you pull the string.
Summary: Reduce swelling with cold water. Lubricate your finger. Try the string method if lubrication doesn’t work. Wrap the string around your finger. Pull the bottom end of the string to unwind it.

In one sentence, describe what the following article is about: Put in shelves along one long wall, and you've got a great place to show off your collection. Use several rows of shelves in a single color to pull the look together. Mirrors can make any space look bigger because they reflect light and space. Try adding repeating mirrors in a decorative shape, such as a series of oval mirrors in a row or a repeating pattern of diamond-shaped mirrors. When you're decorating a wall, you're likely to think of 2-dimensional art, such as prints and paintings. When all your decorations are flat against the wall, the effect can be flat as well. However, adding 3D art can give the wall texture and depth, making it more interesting, because it pulls the decorations partially out from the wall..  For instance, try displaying a collection of plates that come out from the wall, or use large fake silk flowers to cover part of the wall. You could also hang thin decorative lights from the ceiling near the wall to bring the decorations out from the wall. Paintings that are partially sculptures, meaning they have 3D aspects to them, also work well. Hang a tapestry on the wall for a dramatic effect. You can even use a decorative rug on the wall as a tapestry. However, if those options are too expensive, opt for a decorative (hemmed) fabric or even a cheap sheet. Keep in mind that larger prints will work better for a wall. Also, be sure to iron the fabric first.  You can use a tapestry rod to hang it, but if you want to go cheaper, try painting wooden dowels from a home improvement store. Create a sleeve at the top and bottom by simply turning the edge over and sewing across or using fabric glue. Insert the rods, and hang the top rod from hooks. Another option is to staple a piece of fabric over a canvas.
Summary:
Show off your collectibles. Use mirrors. Add texture with 3D effects. Create a tapestry effect.
