Problem: Article: Math can be a difficult subject, especially if you don’t have a firm understanding of some of the most basic concepts. More advanced mathematical ideas build on more basic ones, so it is not a bad idea to review concepts and ideas that are a little fuzzy, until they become perfectly clear. For example, brush up on Addition, subtraction, multiplication, and division. These are crucial parts of math, and having a firm grasp on them will help you out in more advanced fields of math, including algebra and trigonometry. It’s tough to get better at math if you skip classes. You’ll miss out on valuable instruction if you’re absent, and your math skills remain stagnant. Math skills and concepts are cumulative, meaning that what you learn during week 5 of the semester will build on what you learned during week 4. But, if you skipped classes during week 4, you’ll almost certainly struggle to pick up the concepts taught in future weeks. If you must miss a class (e.g., if you’re sick), email your teacher and ask what information you missed. Politely ask them if you can make up in-class assignments you missed. If you’re a student, focusing and paying close attention to your teacher’s lectures during math class can help you get better in a hurry. Also write down any problems, equations, or figures that the instructor draws on the board. These will be valuable to refer back to if you get stumped while working on math homework outside of class. If you typically sit with a group of friends who whisper or text during class and distract you from what the teacher is saying, move away from them and sit alone near the front of the room. during math classes. As the teacher speaks, jot down detailed notes in your clearest, best handwriting. It’s very likely that what the teacher is saying is important and is something you should remember that will help you study for tests. Writing down what your instructor is saying will help you understand the ideas, and the notes you take will also be a valuable resource when you’re studying for a test or quiz. You can take notes either on paper or in a word-processing document on your computer. However, if you have a tendency to get distracted on the internet while you’re taking notes with a computer, stick to taking notes on paper. If you feel that you don’t have a firm understanding of the math you’re learning, your first step should always be to talk to the teacher. If you’re confused or don’t understand the concepts your teacher is lecturing on, raise your hand and ask a question! In reality, you are probably not the only one confused, and other students will appreciate your question too. For example, you could say something like, “I’m really struggling with understanding imaginary numbers, and I’ve read the textbook chapter a few times. Could you explain them to me again?”
Summary: Brush up on basic math concepts to help with more difficult ones. Attend every math class to ensure you don’t miss information. Listen closely during class to boost your grasp of math concepts. Take thorough, detailed notes Ask your math teacher for help if you’re struggling with the work.

Problem: Article: Don't leave evidence of your snacking behind or your teacher will know that you were eating in class. Hide the trash in your school bag until class is over and then toss it out in a trash can or recycling bin. Don't throw your trash away in your classroom's trash can. Your teacher may notice and connect the dots that you've been eating in class. Leftover crumbs might get you busted with your teacher. Don't wipe the crumbs onto the floor. Instead, wipe them into the palm of your hand and then dump them into a plastic bag in your school bag. Throw the bag of crumbs away after class. If you know you're going to be snacking in class, bring a couple paper towels in your bag. When class is over, look around your desk for any greasy smudges or drink spills. Use the paper towels to wipe them up. Stash the used paper towels in your bag and throw them away when you get out of the classroom. Don't get upset or have an attitude with your teacher. At the end of the day, you were breaking the rules and you should say you're sorry. Your teacher will be less angry with you if you show genuine remorse for eating in their class.
Summary: Throw away any wrappers or trash after class. Don't forget to wipe up crumbs on your desk. Clean up spills and grease streaks. Apologize if you get caught eating in class.

Problem: Article: Unlike most knots, the Pratt knot begins with the tie upside down, so the seam of the tie is facing forward. Hang the wide end of the tie over your right side, and the narrow end over your left side. This medium size knot suits most collars and builds. In a knotted tie, the wide end should just graze the top of your belt buckle. At the start, however, raise or lower the wide end until it hangs 1–2 inches (2.5–5 cm) below this point. As a rule of thumb, the Pratt knot will lift the wide end by this distance as you tie the knot. The narrow end of the tie should be higher than the wide end. It will usually be around belly button level, but this is less important than the wide end's placement. Move the wide end across your body to the left side, placing it underneath the narrow end. Do not move the narrow end of the tie for any part of this knot. Just hold it steady while you use the wide end.
Summary: Place the tie upside down around your collar. Check the position of the wide end. Cross the wide end under the narrow end.

Problem: Article: PHP is a scripting language that you can use to build interactive scripts. These scripts are executed on the web server and then the results are returned to the viewer via HTML. PHP allows for very interactive and user-focused websites. MySQL is an open-source database language. It allows you to create, edit, and access multiple databases on your server. The combination of these two is essential for online stores, forums, games, and more.   PHP can collect form information from the user, create and edit files on the server, send and receive cookies, restrict access, encrypt data, and much more. In order to use PHP and MySQL, you will need access to a web server. If you don't have access to a web server, you will need to install one on your own computer.   This guide will show you how to find a cheap, reliable web host. This article will show you how to create your own web server. There are a variety of ways that you can learn the ins and outs of PHP and MySQL coding. There are online resources, online courses, books, and classroom courses. All of these can help you learn PHP and MySQL.   The most popular online resource is w3schools.com. This is the premiere web development instruction website, and quickly covers the basics along with interactive tutorials. There are a variety of books available as well. Some of the most popular books include “Learning PHP, MySQL, JavaScript, & CSS” by Robert Nixon and “PHP and MySQL Web Development” by Luke Welling. Check the course listings for your local community college. There may also be programming schools in your area, or classes led in community centers. Hands-on classes led by professionals can be great for getting questions answered and seeing the code in action. To begin creating PHP scripts and MySQL databases, you will need to download a few basic tools. While PHP can be edited in any text editor, you will find that using a dedicated coding editor will make your life a lot easier.   Popular free editors include Notepad++, Komodo Edit, NetBeans, and Eclipse. Popular paid programs include PhpStorm, Adobe Dreamweaver, and PHP Designer. In order to use MySQL, you will need to have it installed on your web server.
Summary:
Understand what PHP and MySQL are. Rent or create a web server. Find some resources. Download the necessary tools.
