Problem: Article: PEMDAS is an acronym to help you remember the order of operations in math. PEMDAS stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. Whenever you are solving a problem, start with the expressions in parentheses and work your way through the acronym, finishing with subtraction.  For parentheses, perform all of the operations inside the parentheses using this same order. Multiplication and division are considered equal operations. You can solve them at the same time, so simply solve from left to right. Addition and subtraction are also equal operations, so solve from left to right. You can remember PEMDAS using the mnemonic, Please Excuse My Dear Aunt Sally. For any problem you solve in algebra, you will always solve it using this order. Many times, a problem has parentheses to denote all of the operations you will perform first. Multiplication and division rank equally, so simply solve either of these operations from left to right. The same goes for addition and subtraction. For example, to solve the equation (3+6)×7−42{\displaystyle (3+6)\times 7-{\frac {4}{2}}}:  First solve the expression in parentheses:(3+6=9){\displaystyle (3+6=9)}9×7−42{\displaystyle 9\times 7-{\frac {4}{2}}}  Next, solve exponents. In this particular equation, there are no exponents, so you can move on to the next step. Next, multiply and divide left-to-right:63−42{\displaystyle 63-{\frac {4}{2}}}63−2{\displaystyle 63-2}  Finally, add and subtract left to right:63−2=61{\displaystyle 63-2=61} The more problems you practice, the better you will be at solving them. Eventually, using this order of operations will become second nature and you won’t even think about it. Do as many problems as you need to feel confident in solving them.  Example 1: 8+(6×42+7){\displaystyle 8+(6\times 4^{2}+7)}=8+(6×16+7){\displaystyle =8+(6\times 16+7)}=8+(96+7){\displaystyle =8+(96+7)}=8+103{\displaystyle =8+103}=111{\displaystyle =111}  Example 2: 302+52−(6×3){\displaystyle {\frac {30}{2}}+5^{2}-(6\times 3)}=302+52−18{\displaystyle ={\frac {30}{2}}+5^{2}-18}=302+25−18{\displaystyle ={\frac {30}{2}}+25-18}=15+25−18{\displaystyle =15+25-18}=40−18{\displaystyle =40-18}=22{\displaystyle =22} When starting to learn algebra, the material can get overwhelming very quickly. Don’t be afraid to ask your teacher for help or seek out extra tutoring. Even asking a friend who may have a better understanding can be useful. Ask your parents about getting a tutor if you are really struggling.
Summary: Memorize PEMDAS. Use PEMDAS to solve problems. Practice with some examples. Ask for help.

In one sentence, describe what the following article is about: Ideally, your dog should be socialized to the stairs when he's a puppy. Fortunately, if he wasn't, your adult dog can be introduced to the stairs in the same way as a puppy. Look at your dog's size and decide on an appropriate start. For example, if you have a large breed dog, take him over to a regular house stair. If you have a miniature or toy dog, stack up two or three books to make shallow steps. If using books, make sure the cover is not slippery and they are stable. Or, wrap the books in towels to give your dog some traction. Place a treat that your dog enjoys on the first step. This will make him interested in climbing up the stair. Encourage him to step up and get the treat. Use kind words spoken in a soft voice, especially when he makes an exploratory move like moving his paw onto the step. Once he jumps onto the first step, give him the reward and praise. For example, say, "Go on boy. Get it." When he does jump up, you could reward him and say, "Brave dog!" Your dog may feel stranded up on the stair, so lure him back down with a treat. Have your dog practice going up and down the first step over several training sessions. Eventually, your dog should go up and down the first step confidently. At that point, start working on the second step. If your dog is hesitant to go back down, you might want to make the drop from the step to the ground shallower. For example, set several books on the ground and place the treat on top of them. Don't feel like you can only reward your dog when he successfully climbs the stairs. Instead, reward and encourage small improvements like looking towards the step or touching it with a paw. You should be helping your dog build positive associations with the stairs. This will reduce his anxiety. Try to make the stairs fun for your dog. Treat training like a game and your dog will be more likely to try climbing them.
Summary: Introduce your dog to the stairs. Lure your dog onto the first step. Motivate your dog to get back down. Praise your dog's efforts.

In one sentence, describe what the following article is about: Your cursor will turn into a small cross-hair reticle. A grayed rectangle should appear where you drag your cursor. If you need to adjust your windows at all, press Escape to return to a regular cursor without taking a picture. You should hear a brief camera shutter noise if your computer's sound is turned on. That signals that your screenshot has been taken. It will be saved as a .png file named "screenshot" labeled with the date and time. Earlier versions of OS X will save it as "Picture #"—for example, if it's the 5th screenshot on your desktop it will be labeled as "Picture 5". Once you have taken your screenshots, they are now ready to be used as needed. You can attach them to an email, upload them to the Web, or even drag them straight into an application such as a word processor.
Summary:
Press Command + Shift + 4. Click and drag your cursor to highlight the area you'd like to take a picture of. Let go of the mouse. Find your screenshot on your desktop. Use the screenshot.
