Article: There are several functions on the calculator that will be essential for Algebra, Trigonometry, Geometry, Calculus, and more. Find the following functions on your calculator:   Basic Operations    Operation  Function     +   Addition     -   Subtraction (not negative)     x   Multiplication (There is often an x key for variables as well)     ÷   Division     ^   Raise to the power of     yx   y to the power of x     √ or Sqrt   Square root     ex   Exponential     sin   Sine function     sin-1   Inverse sine function     cos   Cosine function     cos-1   Inverse cosine function     tan   Tangent function     tan-1   Inverse tangent function     ln   Log to the base of e     log   Log base 10     (-) or neg   Denotes negative number     ()   Parentheses for denoting order of operations     π   Inserts pi     Mode   Switches between degrees and radians While the bulk of the most common functions will have their own keys (e.g., the SIN key), things like inverse functions (e.g., SIN-1) or less-common functions (e.g., the square root √) will be listed above other keys.   Some calculators have a "Shift" key instead of a "2ND" key. In many cases, the color of the "Shift" or "2ND" key will match the color of the function's text. Whenever you type a left parenthesis, you must close it with a right one; similarly, if you type a total of five left parentheses, you'll have to close them with five right ones. This is important when entering larger calculations, as leaving out a parenthesis can cause the equation to return a far different answer than you should have. You can change between displaying values in terms of degrees (fractions of 360) or radians (decimals using pi as the basis) by pressing the MODE key, using the arrow keys to select RADIANS or DEGREES, and pressing the ENTER button.  This is important when performing Trigonometry calculations. If you notice that your equations are returning decimal values instead of degrees (or vice versa), you'll need to change this setting. Saving your results and pulling them back later is an essential skill for dealing with longer problems. There are a couple of different ways to use stored information:  Use the Answer function to recall the last displayed answer to an equation. For example, if you just entered 2^4, typing in -10 and pressing ENTER would subtract 10 from the solution. Press STO after retrieving your preferred answer, press ALPHA, select a letter, and press ENTER. You can then use that letter as a placeholder for your answer. If you ever need to exit a menu or remove several lines' worth of equations from the calculator screen, you can press the CLEAR button near the top of the keypad to do so. You can also press the 2ND or Shift key and then press whichever button has "QUIT" listed over it (in most cases, this is the MODE key).
Question: What is a summary of what this article is about?
Find the important functions. Familiarize yourself with secondary functions. Always close your parentheses. Switch between degrees and radians. Learn how to save and restore. Clear the screen.
Article: Every day, when you wake up, express three things for which you are grateful. Perhaps you have a job you love. Maybe you have a very supportive partner. You might have no illnesses. Always taking a moment to reflect on the things for which you are grateful can be very helpful.  See Express Gratitude for ideas on how to express your gratitude to others. Practice counting your blessings before bedtime by journalling about three positive moments from your day. Contemplate why these moments occurred and what actions of yours did or did not lead to them. Part of living a good life is not getting wrapped up in the daily problems we all face. While it is important to Handle Problems, take a moment to think about what is going well in your world. Perhaps you saw someone escort an elderly lady across the street. Maybe the children at your local school are collecting food for the homeless. Do you still have your health? Are you not penniless? Do you still have loved ones? Though you might be missing some of these things, keeping your problems in a relative position is helpful. One way to be grateful for life and to enjoy life is to engage with nature. Ride your bike along the river or take a walk in the forest. Listen carefully for the different animals’ and insects’ noises. Smell the plants or fresh rain. The world is filled with amazing attributes. Take a moment to let it sink in. Consider taking a reflective, multi-sensory walk in which you do not focus on any technology. Rather, look around you, notice different buildings or trees in your environment. Focus on the smells coming from a bakery or fresh-cut grass. Listen to people's voices or the wind in the trees. Sometimes to appreciate the good things we have in life, we need to take a pause from them. The pause could be a week or a month. When we return to our activities, we are more likely to realize how lucky we are to have them. For example, perhaps you have a pumpkin latte every day in October. Try taking a week off. You will appreciate the drink and its impact on your happiness even more.
Question: What is a summary of what this article is about?
Contemplate gratitude. Keep problems relative. Get outside. Abstain from pleasurable activities temporarily.
Article: Take a moment to notice the quality of your breath. Notice if you are breathing in through your mouth or through your nose. For now, don’t try to change your breath. Just notice how it feels and breathe naturally. Try breathing in through your nose and down into the lower depths of your belly. Then, while you are exhaling, say “hello.” Listen to the pitch and depth of your voice. To compare, try the same exercise but breathe into your chest or your throat. It should sound very high pitched when you breathe into your throat, medium pitched when you breathe into your chest, and deep when you breathe into your lower diaphragm. Breathe deep into your lower diaphragm. As you exhale, say something you want to say. Your voice will sound deeper if you breathe into your lower belly.  Open your mouth quite naturally, in order to speak normally. Do not purse, cup or shape your lips or cheeks.

Breathe naturally. Experiment with your breath. Use diaphragm breathing.
