In one sentence, describe what the following article is about: A digital electric meter records the amount of electricity your household is using electronically. Thus, a digital electric meter is much simpler to read than a traditional meter because it has fewer readings to decipher. Unlike traditional analog electric meters, many digital meters transmit your meter reading wirelessly to the electric company via radio frequencies. This means that you will not have a meter reader come to your house to read your meter. If you prefer to keep your traditional meter, it may be possible in some municipalities to avoid having a new "smart" meter installed. Your meter should have a digital readout that gives you one long series of numbers. The exact configuration on this readout will vary depending on the manufacturer and the readout could include .  Contact your electric company to get information about your meter if you cannot figure out how to read it on your own. Your electric meter may have a few other numbers displayed, including power status for the meter and reference numbers for the electric company. Remember to only pay attention to the large central string of numbers when trying to figure out your electric usage. Digital electric meters do not reset after every reading. This means that in order to calculate the number of kilowatt hours you have used, you need to keep track of consecutive readings. Subtract the current reading from the last reading you were billed for to get the most recent kilowatt hours used.
Summary: Understand the different parts of your meter. Read the numbers on your meter. Calculate the kilowatt hours you have used.

Look around at all the floor that will need to be covered. This includes everything bordered by walls, but also less obvious places like the floor inside of closets. Sketch the floorspace out on a sheet of paper for reference. Run a tape measure down one side of the room to get its length. Move the tape measure and record the other wall in the same way. Write these measurements down on the sketch you made for reference. If there aren’t any obstructions or unusual aspects to the room, the length and width will be enough to calculate the area. Take the length and multiply it by the width to get the area of floor space in square units. For instance, if one wall is 10 feet (3.0 m) and the other is 8 feet (2.4 m), multiply these to get a total floor space area of 80 feet (24 m) square. If there are any closets, obstructions, or angled areas in the room, you’ll start with this basic area and adjust it with a few more calculations to get the actual total amount of floor space. If you have a simple room with no obstructions or unusual shapes, look up an online floor space calculator. Enter the length and width measurements, and the calculator will compute the area.

One-sentence summary -- Map out the entire floorspace. Measure the length and width of the room. Multiply to get the area. Use an online calculator for a quick solution.

Problem: Article: Pour 4 parts of water into a saucepan on your stove and set the burner on high. As the water warms, add in 1 part of white sugar. Bring the water to a low boil, and let it boil for 2–3 minutes so the water and sugar blend. Then, let the water cool for 30 minutes, and pour it into your feeder.  The size of the carafe varies from one hummingbird feeder to another. Only make enough nectar to fill the carafe of your feeder(s). If you make extra, you can store it in the refrigerator. The nectar will only keep for about 1 week, though. Never use honey or artificial sweeteners in your nectar, and never give hummingbirds commercial foods that contain red dye. Due to the high sugar content of the nectar, the feeders get dirty quickly. To clean them, mix white vinegar and warm water at a ratio of 1:4. Dump out the old, dirty water, and pour in about 1⁄2 litre (0.13 US gal) of the vinegar solution. Place the lid back on the feeder and shake it vigorously to clean out the feeder. If the inside of the feeder is especially dirty, drop 12–20 grains of rice in along with the vinegar mixture. The rice will scrape stains or moldy patches out from the carafe. Once it’s clean, rinse the feeder out 2–3 times with warm water to remove all traces of the vinegar mixture. If any vinegar is left inside, birds will stop drinking from the feeder. Then, refill the feeder with another batch of sugar water for the birds to eat. Hang the feeder again, and watch as more of the beautiful birds come by to drink! Ants are a problem for all hummingbird feeders, but get especially bad with suction-cup feeders, since ants have easy access to them. Prevent ants from accessing your feeders by filling up the feeders’ ant moat with water. The ant moat is a 3–4 in (7.6–10.2 cm) wide trough that goes around the feeder. When ants attempt to get to the sweet nectar, they’ll fall and drown in the moat. At least once a week, scoop the ant bodies out of the ant moat and dispose of them.  Most saucer and J-hook feeders have ant moats. Suction-cup feeders often don’t, since the moat would be unable to wrap all the way around the feeder. If you’re concerned about ants and wasps getting into the nectar and bothering the hummingbirds, purchase a bee guard that can be attached to the feeder. Most hardware stores sell bee guards.  Never fill the moat with oil. Small birds will drink from the moat from time to time, and the oil could harm them. If you don’t take preventative steps, you’ll soon find that your feeder is full of drowned ants and that the birds are no longer drinking from it.
Summary:
Fill the hummingbird feeder with nectar made from sugar and water. Clean the feeder with vinegar and warm water once a week. Rinse the carafe with warm water and refill the feeder. Keep ants away by filling the feeder’s ant moat with water.
