INPUT ARTICLE: Article: As she is your girlfriend, you should be thinking about her. When you do, let her know. A simple text message or phone call if you are apart, or a gentle touch on her back or arm if you are together, are small ways to let her know you care.  Try a simple message: “Just wanted to let you know I'm thinking about you.” A little gesture like this may make her day. Bring up a recent memory. For example: “I can't stop thinking about the time I accidentally dropped all the eggs on the floor and you slipped on them! It's been making me laugh all day.” Begin with a compliment: “Your beautiful smile has been on my mind all day today!” Subtle actions can go a long way with your girlfriend. Using your manners and going out of your way to be particularly polite and thoughtful around her will be highly appreciated. However, you should look to reach an agreement about the type of thoughtful behavior that she will appreciate. Talk with your girlfriend early on about which types of traditionally courteous behaviors fit into your lives and which do not. For example, you may want to pull out her chair for her, but she may find this patronizing. Communicating about these behaviors will help avoid any misunderstanding. Here are some suggestions for courteous behaviors she may appreciate:  Open the door for her. This move has been appreciated by women for centuries! Walk on the outside of the sidewalk, closest to traffic. This is a quiet sign of protection. Put your arm around her in busy, public places. Offer to pay the bill at dinner. Even if she refuses and asks to split the bill, your offer will not go unnoticed. Introduce her. It might bother her to be standing next to you chatting with a crowd of your friends when none of them knows her name. Make sure the first thing you do is introduce your girlfriend. This will make her feel important to you and let her relax a bit in conversing with your friends. . Whether you are alone, amongst friends, or at a crowded bar of strangers, let her know that she is the one who has your eye and your heart.   Make eye contact with her from across the room. Let her know she's the only one on your mind without having to say a single word. A smile always helps. Take her feelings into consideration. For example, when you are making plans, discuss them with her. Make her feel like half of a couple. Compliment her. Whether it's a new outfit, a new haircut, or simply the way her smile lights up the room, tell her you've noticed and approve (even if you don't completely!) Spoil her a little bit. Has she been eyeing a certain scarf at the mall? Buy it for her and give it to her as a “Just Because It's Thursday” present. Thank her when she brings you something, helps you with something, or does something kind for you. A simple "thank you" can mean a lot and will make it more likely she'll go out of her way for you in the future. Better yet, thank her for no reason at all -- just for being herself. An unexpected kindness will warm her heart for days. Your girlfriend's friends (and family) probably play a huge part in her life. They will have some influence on her. If you're going to make this relationship work, you will want to try to gain the approval of her close friends of either sex.   Show interest in her friends. Ask them the same questions you asked her when you were getting acquainted. A great place to start is asking her friends how they met your girlfriend.   Prove she's in good hands. Show her friends that you genuinely care about her, but don't push it too hard. Hold her hand, perhaps, but don't display affection to the point of embarrassing anyone. Speak highly of her. Her friends don't want to see you making fun of her or putting her down. While light jesting can be okay, save that for when you know her group a bit better. For the first few meetings, just be quietly but firmly complimentary. If you can't get along with her crew, minimize your contact with them. Just let her know that you approve of her spending time with them and that you won't feel jealous of them as a result. A surprise can be as big or as small as you want it to be. Something unexpected will make her feel loved and treasured. Here are some simple suggestions:  Leave her a note on her bathroom mirror. If you get up for work before she does, leave her a quick “I love you!” note somewhere she'll be sure to notice. This will undoubtedly make her smile, and she'll think about it all day. Send her a card in the mail for no reason. It doesn't have to be a holiday. Getting something in the mail will be a pleasant surprise. Send her flowers. Use a website like www.proflowers.com to choose a bouquet that is perfect for her, and have them delivered to her home or work. You may not care about flowers, but she does. Plan a surprise date. Text her: “See you at 7 at my house”, and have a candlelit home-cooked dinner waiting for her when she walks in the door. She will remember this for the rest of her life. This doesn't mean you need to engage in periodic, public displays of affection, but it does mean you treat her in a way that you don't treat any other woman. She enjoys feeling special to you.   Hold her hand when you go for a walk. This simple and sweet action will show her that you're proud to call her yours. Wrap your arm around her when it's cold. This gesture will show her you care for her and want to take care of her. Kiss her on the cheek. This is a tender move that shows her that you care. Whether she's in an argument with a friend or having a problem with her boss, take her side. This doesn't mean you need to find her faultless in every situation, but it does mean that you should be a source of support for her, even if later, when things have calmed down, you point out that she might not have been completely right.

SUMMARY: Let her know you're thinking about her. Show her courtesy. Make her feel special Get to know her friends. Surprise her. Be affectionate toward her. Stand up for her.


INPUT ARTICLE: Article: The central limit theorem states that the sum of a number of identical dice approaches a normal distribution as the number of dice increases. Assuming n dice numbered 1 to r, the formulas below apply.  The mean is  (r+1)/2. The variance is n(r^2-1)/12. The standard deviation is the square root of the variance.

SUMMARY: For a large number of dice, exact computation by the above methods may be difficult. Compute the mean and standard variation based on the number and type of dice. Use the normal distribution with the above mean and standard deviation as an approximation of the sum of the dice.


INPUT ARTICLE: Article: If you're confident finding frets and strings quickly, you can move past this step and onto reading tabs. However, it never hurts to review some guitar basics:   Fretting: The small metal strips on the guitar neck. If you're right-handed, then the first fret is the one farthest to the left. To play a fret, you push the string down just to the left of fret (right-handed). So, to play the 3rd fret you'd play just to the left of the third metal strip, so your finger is between the second and third frets.  Strings: The six strings are ordered, starting from the thinnest string on the bottom, as eBGDAE. The thinnest string is the 1st string, the thickest string (on top) is the sixth string.

SUMMARY:
Review the basics of fret and string numbering.
