Problem: Write an article based on this summary: Know why you need to warm up. Try a light aerobic workout to get your blood pumping. Do stretches. Do crunches or sit-ups. Stretch your wrists and arms. Stretch your neck.

Answer: Warming up is important because it stretches out your muscles and literally warms them up. It can help prevent injury. For instance, you can do jumping jacks or walking push-ups. For jumping jacks, start with your arms and legs straight together. At the same time, jump your legs out to about shoulder length and bring your arms up by your head. Jump back to the original position and repeat. For walking push-ups, do a couple of push-ups like normal, and then stay in the same position to move over four steps. Do more push-ups. Stretching will help you be more flexible when you do actually start dancing. For instance, try hamstring stretches. Sit on the floor with one leg bent away. Stretch the other leg out in front of you. Let the outstretched leg pull inward while leaning forward. Hold for half a minute. Repeat a few times, and then switch to the other leg. These moves build strong core muscles, which makes it easier to perform all types of dance moves. In breakdancing, weight is often carried on the arms and wrists, so you need to ensure they are flexible enough before starting. Holding your arm out, move your hand back and forth to slowly stretch out the muscles. With you arm still outstretched, flipped your hand over and back several times. To stretch out your forearms, place your palms together in front of you with your elbows out. Rotate your hands forward, stretching the muscles, and then rotate them back. You will be using your head and neck for balance. Standing straight, gently roll your neck in a circle, loosening your neck muscles. Repeat, moving in the opposite direction. Looking straight ahead and gently grab the side of your head, pulling your ear toward your shoulder and holding for a few counts. Do the same on the opposite side.

Problem: Write an article based on this summary: Take a deep breath and try to stay calm. Avoid yelling or showing that you're overwhelmed. Try to figure out if your child is whining for a legitimate reason. Don't give them what they want while they're whining.

Answer: Try not to let your child's whining drive you crazy. Inhale slowly, do your best to maintain a reasonable mindset, and keep your frustration in check. You'll have better luck dealing with your child's whining and addressing any legitimate needs if you keep your cool. Scolding your child can negatively reinforce their behavior, or show them that they can get attention if they whine. Furthermore, if you immediately yell at them to stop, they might burst into a full-blown tantrum. Remind yourself that children whine when they want or need something, feel powerless, or lack the words to express themselves. Instead of yelling, figure out what's motivating their behavior and instruct them to communicate nicely. If your child is whining without saying actual words, try to get to the bottom of their behavior. For example, think about when they last ate, slept, or went to the bathroom. While their behavior might be unacceptable, they might be upset for a legitimate reason. It's important that you don't immediately cave into their demands while they're whining. This lets them know that whining is a good way to get what they want. Instead, your goals should be to help them express themselves calmly, then address any legitimate needs.

Problem: Write an article based on this summary: Get a lighter. Take off the cover. Adjust the wheel. Turn it back to the left. Set it down and repeat. Turn it on. Make the flame bigger.

Answer: You can buy these from most small stores. It should snap or pull off but you can also use pliers. Turn the adjustment wheel all the way to the plus side (usually the right). Lift the tab up so that it isn't touching the wheel and turn the tab all the way back to the left. You can do this several times to turn it up as much as possible. Be careful. You should get a 3"+ flame. You can readjust as necessary. Take it up a notch by spraying WD-40 or engine degreaser at the flame. Hold both far from your body and away from other people and flammable objects. It will make a HUGE flame.

Problem: Write an article based on this summary: Start with mean and median. Learn the connection between variance and mean. Understand the connection between variance and standard deviation. Learn to calculate normal distribution.

Answer:
Mean and median are 2 of the most basic statistical concepts, and they're foundational to other, more complicated concepts. The mean is the average of a set of numbers, and the median is the middle of a set of numbers. Your text book should cover these concepts and how to calculate them at the very beginning. You can also find instructions at on websites like MathWorld. To calculate the mean, add all of the numbers in your data set and divide the sum by the number of numbers in the set. For example, if your data set includes the numbers 2, 4, 6, 8, 10, and 12, the sum of the set is 42. 42 divided by 6 (the number of data points) is 7. 7 is your mean. The median is the just the middle of any set of numbers. So the median of the data set 2, 4, 6, 8, and 10 is 6. If you have an even number of data points, add the 2 middle numbers of divide by 2. Once you know how to calculate mean, you can move on to more complicated concepts. Variance is the average of squared differences from the mean. Knowing the variance can help you understand how spread out a set of data is. For example, let's say you and your 3 friends each have a dog, and their heights are 12in (30cm), 20in (51cm), 16in (41cm), and 32in (81cm). First, take the mean of their heights by adding all 4 heights together and dividing by 4. In inches, this would be 12 + 20 + 16 + 32, which equals 80. Divide that by 4 (the total number of dogs) to get 20. So the mean of their heights is 20in (51cm). Then calculate the variance by subtracting each individual height from the mean and squaring it. So 20 - 12 is 8, and 8 squared is 64. 20 - 20 is 0, and 0 squared is still 0. 20 - 16 is 4, and 4 squared is 16. And 20 minus 32 is -12, and -12 squared is 144. 8 + 0 + 16 + 144 = 168. To get the final variance, divide the sum of the squared differences from the mean (168) by the number of dogs (4). So the variance of this data set is 42. Standard deviation tells you how much each data point differs from the mean. To calculate the standard deviation, you'll need the variance first. Then take the square root of the variance. If the resulting number includes a decimal (most will), round it to the nearest whole number. For example, if the variance of your and your friends' dogs' heights is 42, the standard deviation is the square root of 6.48. You'd round that down to 6. That tells you that, on average, each dog is about 6in (15cm) away from the mean of the dogs' heights. The normal distribution is a graphic distribution of a set of data's mean and the variations from the mean. You can learn a lot about a data set from normal distribution graphs. To learn how to calculate them, you'll need to calculate z values individual points on the graph. A table of z-values can usually be found in your text book. Your textbook should have detailed instructions on how to calculate points on a normal distribution graph. You can also find resources online, at websites like minitab or MathWorld.
