INPUT ARTICLE: Article: Dump out the old one entirely, replacing with fresh, unused litter. The number of cats you live with, the number of litter boxes available to them, and the type of litter you use, will determine how often you have to replace the litter. Replace non-clumping-type litter twice a week at least. For the clumping-type litter, if you scoop the litter box everyday, you can replace it every two to three weeks. If you notice an unpleasant odor or a lot of clumps, replace it sooner. Every time you replace the litter, wash the box thoroughly. You can use some mild detergent like dish soap and warm water. The packaging labels usually tell you if the product is mild or not. Empty all the litter in the box. Gather your detergents and a disposable sponge or cloth. Avoid using detergents that contain ammonia, bleach, citrus oils or those with strong smell; these substances could turn cats away. Some cleaning products, including laundry detergents, toilet-bowl cleaners, and disinfecting wipes, can be toxic to cats. Check the label for any warnings such as ""Keep pets and children away from area until dry" A litter-box liner may make it much easier when it comes time to replace the litter. Litter-box liners are designed to hold the litter, just like a bag, making for easy removal and disposal. Use a litter-box liner for easy disposal. In many cases, the liner ends up being shredded by cats, Some cats hate liners, and the use of them may possibly deter your cat from using the litter box.

SUMMARY: Replace the litter. Scrub the box. Consider using a liner.

In one sentence, describe what the following article is about: Alcohol should be used sparingly when cleaning your printer rollers. Avoid using other kinds of solvents altogether. These products can dry out the rollers and cause them to become cracked and damaged over time. Using these kinds of products could also void any kind of manufacturer's warranty that you may have on your printer. If your printer seems to be having trouble feeding paper through, take a few moments to resolve the problem by cleaning the printer rollers. Don't just keep trying to make the printer work, as this will just exacerbate the problem. Maintaining your printer regularly and treating it with care will give the machine a much longer life expectancy. Whenever you perform any kind of maintenance or cleaning on your printer, unplug the machine before you begin. Leaving the printer powered on or plugged in could lead to potentially damaging the machine or yourself. You don't want to accidentally electrocute yourself or void your manufacturer's warranty on the printer.
Summary: Refrain from over-cleaning rollers with alcohol. Avoid overloading your printer. Unplug your printer while cleaning.

These two scales are typically fixed in place. Simply slide the metal cursor to a value on the D scale, and the A value will be its square. Just like a multiplication problem, you'll need to determine the position of the decimal point yourself. For example, to solve 6.12, slide the cursor to 6.1 on the D scale. The corresponding A value is about 3.75. Estimate 6.12 to 6 x 6 = 36. Position the decimal point to get an answer near this value: 37.5. Note that the exact answer is 37.21. The slide rule answer is off by less than 1%, easily accurate enough for most real-world circumstances. You've just seen how the A scale, which is a D scale shrunk to 1/2 scale, lets you find the square of numbers. Similarly, the K scale, which is a D scale shrunk to 1/3 scale, lets you find the cubes. Simply slide the cursor to a D value and read the result on the K scale. Use estimation to place the decimal. For example, to solve 1303, slide the cursor to 1.3 on the D value. The corresponding K value is 2.2. Since 1003 = 1 x 106, and 2003 = 8 x 106, we know the answer must be somewhere between them. The answer must be 2.2 x 106, or 2,200,000.

One-sentence summary -- Use the D and A scales to find squares. Use the D and K scales to find cubes.

INPUT ARTICLE: Article: Start by working in your local film scene or in areas that you can easily get to. Save the money you make so you can make the move to a larger city where more roles are available and movies are frequently made. Consider moving to Los Angeles, Austin, New York, or Atlanta if you're in the United States. Try Vancouver, Toronto, London, or Mumbai for film outside of the US. Search for casting calls on websites like Backstage or Craigslist for local commercials. As you go in for the audition, dress for the part you're playing so the casting directors can easily picture you in the role. Commercial acting is a smaller role, but it will give you exposure to a wide audience and get your face out to the public. Look out for posts on Craigslist that seem too good to be true since they could possibly be scams. Watch for off-site emails or jobs that seem to be paying too high with no needed experience. Once you're where you need to be, get connected and take on roles as an extra, or background actor. Open casting calls for these can be found all over the Internet, but a few places to start off are Backstage, Hollywood Reporter and Variety. Though it may not be a starring role, you can still list an extra role on your resume to show you have experience. Ask around your network for opinions on who to go to and how to get started. Make cold-calls or send inquiry letters to agencies to see if they are looking for new talent to represent. An agent will help you negotiate deals for the roles you take on. Agents only get paid when they find you work. Don't buy into the ones that demand some exorbitant fee even if your schedule stays wide open. Look into organizations like ACTRA, AEA, AGMA or AGVA. Once you are a member for at least 1 year and worked under union, you're eligible to get into SAG (the Screen Actor's Guild). Unions provide you with benefits and insurances while you're working. Annual SAG fees are $201.96 USD and 1.575% of the earnings you make in that year. Check with the union you're interested in to see what their annual rates are. Though it's completely possible to run through all the hoops without it and still find success, having your equity card opens up a number of auditions that otherwise wouldn't be available to you. You either have to get a contract that requires equity standing, be a member of a sister group (like SAG, for example), or accumulate enough credits to meet the standard. It's natural to find the process a bit confusing, so contact a friend or mainstay in your actor's social network for more information on how they received their card.

SUMMARY:
Move to a large city if possible. Look for roles in commercials when you begin. Become an "extra" actor in larger pictures. Get an agent. Get into a performer's union. Consider getting your equity card if you want to do theatre.
