In one sentence, describe what the following article is about: Especially if you don’t have much practice dancing yet, look into taking as many different classes as you can. Focus on hip hop and urban dancing. A big part of being a trainee (and hopefully an idol!) is being able to perform exceptionally, and that includes dancing. If you can’t take actual classes, use the internet to learn new skills. Even if you’re already a great singer, chances are you could still learn something from a coach. If nothing else, they can give you tips to increase your endurance when you perform. If your main skill is dancing, that is okay! But having the ability to sing will increase your odds of getting noticed when you audition to become a trainee. Rapping is an important part of the K-pop lifestyle, and it can also be fun! Listen to more rap music to get an idea of the rhythm and start imitating your favorite artists. If you get caught up on the words, practice tongue twisters to loosen your lips. When you audition, you’ll need to perform songs that the producers already know, but when you’re a trainee, you’ll be working on writing and choreographing your own original music. It’s a good idea to work on both aspects of being a performer. Take a music writing class if you can, and spend a lot of time listening to K-pop and watching music videos so you can start emulating popular styles.
Summary: Take dance classes to become a better and more versatile dancer. Invest in a vocal coach to strengthen your singing abilities. Work on your rapping skills to round out your skill set. Practice writing your own music and perfecting well-known songs.

In one sentence, describe what the following article is about: When you have one or more algebra problems, you must read the instructions carefully. Look for key words in the instructions like “solve,” “simplify,” “factor,” or “reduce.” These are some of the most common instructions (although there are others that you will learn). Many people have problems because they try to “solve” a problem when they really only need to “simplify” it. When you read the problem instructions, you should identify the key words and then perform those operations. Many people feel frustration with algebra when they try doing something that is not really part of the intended problem. The basic operations you will be asked for are:  Solve. You will need to reduce the problem to an actual numerical solution, such as “x=4.” You need to find a value for the variable that can make the problem come true. Simplify. You need to manipulate the problem into some simpler form than before, but you will not wind up with what you might consider “an answer.” You will probably not have a single numerical value for the variable. Factor. This is similar to “simplify,” and is usually used with complex polynomials or fractions. You need to find a way to turn the problem into smaller terms. Just as the number 12 can be broken into factors of 3x4, for example, you can factor an algebraic polynomial.  For example, a simple expression like 5x{\displaystyle 5x} can be broken into factors of 5{\displaystyle 5} and x{\displaystyle x}. For example, the expression x2+3x+2{\displaystyle x^{2}+3x+2} can be factored into the terms (x+2){\displaystyle (x+2)} and (x+1){\displaystyle (x+1)}.   Reduce. To “reduce” a problem generally involves a combination of factoring and then simplifying. You would break the terms of a numerator and denominator into their factors. Then look for common factors on top and bottom, and cancel them out. Whatever remains is the “reduced” form of the original problem. For example, reduce the expression 6x22x{\displaystyle {\frac {6x^{2}}{2x}}} as follows:  1. Factor the numerator and denominator: (3)(2)(x)(x)(2)(x){\displaystyle {\frac {(3)(2)(x)(x)}{(2)(x)}}}  2. Look for common terms. Both the numerator and denominator have factors of 2 and x. 3. Eliminate the common terms: (3)(2)(x)(x)(2)(x){\displaystyle {\frac {(3)(2)(x)(x)}{(2)(x)}}}  4. Copy down what remains: 3x{\displaystyle 3x} ” In algebra, the difference between an “expression” and an “equation” is very important. An expression is any group of numbers and variables, collected together. Some examples of expressions are x{\displaystyle x}, 14xyz{\displaystyle 14xyz} and 2x+15{\displaystyle {\sqrt {2x+15}}}. All you can do to an expression is simplify or factor it. An equation, on the other hand, contains an = sign. You can simplify or factor equations, but you can also solve them to get a final answer. It is important to look for the difference. If you have an expression, like 4x2{\displaystyle 4x^{2}}, you can never find a single “answer” or “solution.” You could find out that if x=1{\displaystyle x=1}, then the expression would have a value of 4, and if x=2{\displaystyle x=2}, then the expression would have a value of (4)(2)2{\displaystyle (4)(2)^{2}}, which is 16. But you cannot get a single “answer.”
Summary: Read the problem instructions carefully. Perform the operations that are instructed. Learn the difference between “expression” and “equation.

In one sentence, describe what the following article is about: For safety, extinguish cigarettes fully before attempting to recycle them. You can do this by throwing the cigarette on the ground, stepping on it, and twisting your foot. You should no longer see any glowing or smoke coming from the cigarette butt. If you have an ashtray, push the cigarette’s lit end into it until the heat and smoke stop. After you extinguish the cigarette, the filter should cool within a few minutes. Place it in a sturdy plastic bag or container. A thick garbage bag is a good choice since it is unlikely to rip or fall apart. Collect the cigarette filters in a plastic bag or container separate from other trash if you plan on recycling them. If you do not plan on recycling the filters right away, store the bag in an appropriate location. Mark the bag so it doesn’t accidently get thrown away with the rest of the trash. Keep it out of the rain and away from animals. Since recycling options usually have you ship the filters to them, it’s important to protect the bag. Shipping companies won’t take damaged or dripping waste bags. You will need over a thousand filters to reach this weight, so you may end up storing it for a while. Collecting discarded cigarettes or assembling a collection bin helps. Otherwise, you can try sending a lighter bag to the recycling company.  Recycling companies generally pay you $1 USD per pound for bags weighing at least 3 lb (1.4 kg). You can always send smaller amounts of filters. However, it’s more efficient to wait until you have a bigger collection.
Summary:
Extinguish the cigarette by grinding out the flame. Move the cooled cigarette to a sturdy plastic bag. Store the plastic bag in a safe, dry spot. Collect at least 3 lb (1.4 kg) of cigarettes if possible.
