When you decompose a number into its various addends, you are breaking that number apart into different sets of other numbers (addends) that can be added together to get the original value. When one addend is subtracted from the original number, the second addend should be the answer you get. When both addends are added together, the original number should be the sum you calculate. This practice is easiest to do when you have a single digit number (a number that only has a "ones" place). You can combine the principles learned here with those learned in the "Decomposing into Hundreds, Tens, and Ones" section when you need to decompose larger numbers, but since there are so many possible addend combinations for larger numbers as a whole, this method would be impractical to use alone when working with large numbers. To decompose a number into its addends, all you need to do is write down all of the different possible ways of creating the original problem number using smaller numbers and addition. Example: Decompose the number 7 into its different addends. 7 = 0 + 7 7 = 1 + 6 7 = 2 + 5 7 = 3 + 4 7 = 4 + 3 7 = 5 + 2 7 = 6 + 1 7 = 7 + 0 For someone trying to learn this concept for the first time, it might be helpful to use visuals that demonstrate the process in practical, hands-on terms. Start with the original number of something. For instance, if the number is seven, you could start with seven jellybeans. Separate the pile into two different piles by pulling one jellybean to the side. Count the remaining jellybeans in the second pile and explain that the original seven have been decomposed into "one" and "six." Continue separating jellybeans into two different piles by gradually taking away from the original pile and adding to the second pile. Count the number of jellybeans in both piles with each move. This can be done with a number of different materials, including small candies, paper squares, colored clothespins, blocks, or buttons.

Summary: Understand the concept. Practice with a small number. Work through all the different addend combinations. Use visuals, if necessary.

Sticky notes can be very helpful for organizing yourself and your house in a number of ways. If you find that you have developed a confusing tangle of cables behind your TV or computer, and it always takes some painstaking work to discover what cables is for what, sticky notes can help. Tear or cut the note down so you just have the adhesive strip left, and then write down the name of the appliance of each cable, "TV," "DVD," "Stereo," etc. Then wrap the label around the appropriate cable, taking care to fasten it tightly in a ring around the wire. If you live in a shared house, you may want to label your food to make sure that none of your housemates eat it. Sticky notes are ideal for this as you can quickly and easily label your supplies just by writing your name on a note and attaching it to your eggs, milk, or anything else. Try to have some restraint when it comes to labelling food. Labelling absolutely everything can seem somewhat over the top. Consider just labelling a few key things that could easily be mistaken for somebody else's. Sticky notes are a convenient and easy way to leave notes and reminders for people you live or work with. Write down a reminder to pick some milk on the way home from work, or that the electricity bill is overdue, and stick it somewhere prominent. Research has shown that people are actually more likely to respond to, and act on, a message or request made on a sticky note than communicated in some other ways. It is thought that sticky notes work so well because it is more personalised. It is also harder to ignore as it sticks out from its environment. Seeing a note stuck on the fridge may make you want to deal with it so you can take it down, and free the fridge door of mess and clutter. You can use sticky notes to make a colourful, visually engaging, and flexible plan or schedule for everything from work, to study, to household chores. If you are making a schedule for everybody's weekly chores, you can write up each chore on a note and arrange them in groups. Once a task has been completed, the person responsible can tear down the note. You can use notes to make meal plan so you know what you will be eating through the week. This could also help you to realise if you need to buy any ingredients. Using sticky notes to make schedules and plans allows you to move around the meals or tasks. You can easily reassign a task to somebody else, or change the meal plan.

Summary: Label your cables. Mark your food. Leave messages and reminders. Make a colourful schedule or plan.

Most fabrics come in 45 inches (110cm) or 60 inches (150cm) widths. You may need to check the fabric you want to use to see what the width is before you calculate this measurement. Check with a store associate if you are unsure. If you are planning to use some scrap fabric for the binding, then measure across the shortest part of the fabric piece to find the width. Use the perimeter measurement plus the 10 inches (25cm) you added and divide this number by the total width of your binding fabric. For example, if the perimeter plus 10 inches (25cm) equals 190 inches (480cm) and the fabric width is 60 inches (150cm), then your result would be 3.2. This will tell you how many strips you need to cut from the fabric to get the required amount. However, you will need to round up your result if you do not get a whole number. For example, if your answer is 3.2, then round up to 4.

Summary: Identify the fabric width. Divide the perimeter plus 10 inches (25cm) by the fabric width. Round up the result.

Take a cucumber that's been washed, and use a vegetable peeler to remove all of the skin. Next, cut the cucumber into -inch (1.3-cm) slices with a sharp knife. To wash the cucumber, rinse it under cool, running water. Dry it with a clean towel or piece of paper towel. If you prefer, you can leave the skin on the cucumber. Pour 6 cups (1.4 l) of water into the pitcher, and mix in the cucumber slices with a wooden spoon. Next, add enough ice to fill the pitcher and give the mixture another stir. For the best taste, use bottled or filtered water in your spa water. Once you have the water and cucumbers in the pitcher, allow the mixture to sit so the cucumber flavor has time to infuse the water. Leave it alone for at least one hour or up to four hours before pouring it into glasses and serving. Place the spa water in the refrigerator while you're infusing the water to ensure that it's chilled for serving.
Summary: Peel and slice a cucumber. Add the water, cucumber, and ice to a pitcher For the spa water, you'll need a pitcher that holds approximately 2-quarts (1.9 l). Allow the water mixture to sit for a couple of hours before serving.
