Article: Fit the teeth of the hinge on the door with the teeth of the hinge on the door frame. Have someone hold the door in place as you attach it to the door frame with screws. If your hinge has screws, use the same ones you removed to reattach the hinge to the door. If it has hinge pins, insert the pins into the interlocking teeth from the top of the hinge and tap them in with a hammer. Hammering in the hinge pins will attach the door to your door frame. Take your doorknob and place it into the doorknob hole. Secure it to both sides of the door with screws and make sure that it works properly. If you've done everything correctly, your new door should be installed!
Question: What is a summary of what this article is about?
Hang the new door in the doorframe. Screw in the hinges or reinsert your hinge pins. Install your new door knob.
Article: This can help you check that your answer is reasonable. To estimate, round whatever numbers you are working with to numbers that you can easily manipulate in your head. Then perform the calculation and note the estimated value. When you complete the calculations using the actual numbers, compare how close your answer is to your estimate. If it is in the ballpark of your estimate, you know your calculations are likely correct. For example, if you are calculating 11,87639{\displaystyle 11,876\div 39}, you can round 11,876 up to 12,000, and 39 up to 40. Then, you can calculate in your head using basic math facts that 12,00040=300{\displaystyle 12,000\div 40=300}. Then complete you exact calculation. If you get that 11,87639=304{\displaystyle 11,876\div 39=304}, remainder 20{\displaystyle 20}, you can see that your answer and estimate are close, and therefore your calculation is likely correct. You shouldn't use a calculator to complete your math work, unless your teacher tells you it is okay. However, there is nothing wrong with using a calculator to check your answer once you have finished calculating. If you discover with the calculator that your answer is incorrect, don't simply change your answer. Go back through your work and see where you made a mistake in the calculating process, then show the necessary work needed to find the right answer. If you don't show your work on a math problem, your teacher might think you did everything on a calculator and won't give you any credit. Inverse operations are opposite operations that undo one another. Addition and subtraction are inverse operations. Multiplication and division are inverse operations. You can create true equations with the same three numbers using inverse operations. For example, if you find that 56016=35{\displaystyle 560\div 16=35}, you should be able to make a multiplication problem with the same three numbers by multiplying the divisor (the number you are dividing by) by the product: 1635=560{\displaystyle 16 imes 35=560}. If the equation you make with the inverse operation is true, then your calculation is correct.

Make an estimate. Use a calculator. Use the inverse operation.
Article: Use a paintbrush to apply a primer that is specifically for melamine. Target all of the areas that you cannot easily reach with a roller. Primers that are specifically for laminate wood are an alternative option. Roll the primer in one direction across each surface. Ensure that the roller always sounds crinkly and wet, and if it loses that sound, apply more primer. If you are using a new roller cover that has fibers, wrap it in masking tape before you use it. Rip off the masking tape to remove any loose fibers that would have otherwise been stuck to your project. Use 220 grit sandpaper to smooth over any drips or other marks caused by the primer. Wipe over the sanded surfaces with a tack cloth again. The instructions that are on the primer will indicate how long it will take to dry. This normally takes around 4 hours. Cover the full surface of the kitchen cupboards or furniture again. Wait for the primer to dry. You don't need to sand the surface again after the second coat of primer, unless you notice more bumps or imperfections. Use a foam roller to evenly coat all surfaces with paint. Let the first coat dry for 6-8 hours. If you prefer to use a paint brush, brush against the grain first and then brush with it. Paint applied to melamine takes longer to dry than on wood. This is because melamine isn't as absorbent. You can buy paint specifically for melamine surfaces from home improvement stores. Use either a foam roller or paintbrush again to apply paint to all of the surfaces. Let the final coat dry for 24 hours. Start with the back or inside of any doors to cupboards, so that you can get used to spray painting there first. Then spray paint your entire project, and let it dry overnight. Wear a respirator mask at all times when working with spray paint. Check that the spray paint can be used on melamine surfaces by reading the label before you purchase it. Apply a second coat with spray paint if you need to once the first coat is dry.
Question: What is a summary of what this article is about?
Apply primer with a paintbrush over all of the edges and corners. Use a roller to apply the primer to the whole project. Sand the primer once it's dry to remove any imperfections. Add a second coat of primer. Apply the first coat of melamine paint over the primed surfaces. Add the second coat of melamine paint once the first is dry. Spray paint your project if you prefer a smoother finished surface.
