Summarize the following:
When a number has an exponent that means you multiply that number by itself as many times as the exponent says. To simplify any number that has an exponent simply multiply it the appropriate number of times. For example: 43=444=64{\displaystyle 4^{3}=4 imes 4 imes 4=64}. If there is a negative sign and no parentheses, the exponent is simplified and then the negative sign gets added: 22=(22)=4.{\displaystyle -2^{2}=-(2 imes 2)=-4.} If there is a negative sign, but the number is in parenthesis, the negative number is part of the exponent: (2)2=22=4.{\displaystyle (-2)^{2}=-2 imes -2=4.} It may be confusing at first to see a variable with an exponent. Just remember, any variable with the same exponent number can be added or subtracted. If the letters are the same, but the exponents are different, they cannot be combined. For example, 6x2+5x2=11x2{\displaystyle 6x^{2}+5x^{2}=11x^{2}}. Similarly, 4xy38xy3=4xy3{\displaystyle 4xy^{3}-8xy^{3}=-4xy^{3}}. On the other hand, 5z+5z2{\displaystyle 5z+5z^{2}} cannot be simplified, since one variable has an exponent, and one does not. If two variables are being multiplied together and they both have exponents, you can add the exponents together to get the resulting exponent. This only applies to variables of the same letter. For example, (x2)(x3)=x2+3=x5{\displaystyle (x^{2})(x^{3})=x^{2+3}=x^{5}}. If you want to divide two variables that have exponents, simply subtract the bottom exponent from the top exponent. This only applies to variables that are the same letter. For example, a6a3=a63=a3{\displaystyle {
rac {a^{6}}{a^{3}}}=a^{6-3}=a^{3}}.

summary: Simplify exponents of numbers. Combine like terms with the same exponents. Add the exponents together when multiplying variables. Subtract the exponents when dividing variables.

Depending on what your relationship with this person is, there are going to be different boundaries based on social hierarchy, family ties, gender and cultural norms, etc. Are you close with this person, or are they relatively new to your life? Determine the nature of your relationship with them and you already have the foundation of healthy communication. Amongst close friends and family there is often more space for being vulgar and less consequences for being awkward. However if we're texting potential lovers, coworkers, business partners, or anyone with whom we have a formal relationship, different rules of appropriateness apply. Keep this in mind when phrasing your text. Starting strong, and composing a meaningful message can help you avoid this problem in the first place. Many people lead busy lives and choose not to respond to texts that are vague or do not have an obvious purpose or appeal. And so a lot of us are more likely to respond to messages that have a clear purpose. Ask yourself these questions: What do I want to communicate? Is there a purpose to what I'm saying? How do I think they will receive my message? You've given a sincere effort at understanding who you're talking to, what you want to say, and how you want to/should say it. So now you know at least that whether or not they respond has less to do with your actual text, than their situation, or the nature of your relationship.

summary: Consider who you're texting. Figure out what you want to say. Write a purposeful and clear message.

Summarize the following:
Before every school year, your school should provide you with a list of the items you need for your grade. If you don't receive one of these before the school year begins, you can usually find them at supply stores like Office Max or Staples. The most common items for middle school include pens, #2 pencils, notebooks, wide-rule loose leaf paper, a 3 ring binder, and scissors and tape. Other materials you may need include a USB flash drive, a TI calculator, index cards, a weekly planner, and a stapler. You don't want to overload your backpack, so try to take only the essentials when you can. For example, having one binder separated into multiple subjects will help save you space compared to multiple folders. You should also try to take two pencils and two to three pens, as well as a highlighter, and your weekly planner. This way, the rest of your space can be dedicated to textbooks and notebooks. You'll have a better idea of exactly what you'll need day-to-day after the first week of class. If you have money for lunch, try to keep it zipped up in an inside pocket. If you don't have one in your bag, try to keep it in a change purse or wallet instead. This will help keep your money safe and together, so you aren't searching all over for it during lunch time. If you have a block schedule with different classes on different days, try separating your materials into marked piles. For example, you can mark everything for one day with a specific color like red, while the other day is blue. Then you can switch them out of your backpack when necessary. Now is the moment of truth; you want to make sure you can fit everything in your backpack and still be able to carry it. Chances are you'll have a locker you can store some things in, but you still need to be able to take everything to and from school each day. Put your binder, notebooks, textbooks, and pencil case in the main part of the bag - in that order. You should then put any extra materials into the front pockets. For example, your calculator, tape, stapler, even markers, and highlighters if they won't fit in your pencil case can go in your front pockets. The front pockets of your backpack are also a great place to keep items like chapstick, tissues, mints, or anything else you want to carry with you.
summary: Get a list of what school materials you need. Plan out what to take in your bag. Use every part of your backpack.
