Math blogs have helped me a lot. They helped me remember some math. For example I had a math blog about decimals and fractions. I look at my own blogs to help me study for review tests. Another blog about negative numbers helped me remember how to do add and subtract negatives. In a way math blogs help me prepare for tests. Another way math blogs help me is to remember stuff. Math blogs help me remember old math that I don't do anymore in classes.  I really need these math blogs for help. I have learned a  lot in pre-algebra. Next year I will be in Algebra. I am really scared because I think that class will be tough. 
    I did know that the math standards will be changing. When I first heard about it, I didn't really know how to react. I am used to the regular tests and not the new one's. I heard that the new tests are going to be similar to these blogs. I will have to write like this in math. I am not ready for a change. 

    The Hardest math for me to learn this year was negative numbers. The reason why it was hard for to learn is because of how they are used in other math. Although it was difficult for me I overcame it. Later I discovered how negative numbers will help me in the future. One way negative numbers will help me in the future is it will help me with money. Negative numbers will help me determine if I owe money or not. For example if I owed somebody I would be -10. If I had money I would be +10. This is how negative numbers will help me in the future. 
   In the sixth grade negative  numbers were very easy. In the sixth grade I was asked problems like this: -9+3. These problems were easy and I would know the almost instantly. Now I get asked problems with negative numbers in inequalities. 

      Science and Math are very similar. One way they are similar is because they both use math. In some science, math is needed to solve certain problems. Math is used in Science a lot. Without math some science would not exist today. Another way they are similar is because they are used in our daily life's everyday. There are Scientist and Mathematicians. Science and Math are also very important. Without Science we wouldn't have discovered much. Without Math we wouldn't have discovered certain things either. Math and Science are also taught at school. Another way Science and Math and science are related is because science is used in some math. 

     Today I will explain how to solve 2x-7=15. First you need to add 7 to both sides. Add 7 with the -7 and that becomes 0. Cross that out or get rid of it because you do not need it anymore. Then add 7 to 15 and you should get 22. The equation should look like this: 2x=22. Next you will need to divide the 2 on each side as well. 2 divided by 2 is gone so get rid of it. 22 divided by 2 is 11. The equation should look like this: x=11. The answer is 11.

       Today I will blog about how to turn a Decimal into a Fraction. One way that I use is to put a 100 over a decimal. It would look like this, .53/100. I think that it is the easiest and quickest way to convert a fraction to a decimal. I remember using this method in elementary school. It was not that hard to learn either. Another example is .89/100 or .9/10. I am just thinking about some examples right now. I am reviewing this in my math class. This method is easy and fast to use. Also it helped me with other problems too. This method is the best method to use when you are converting Decimals to Fractions. Without this method I would not know how to convert Fractions to Decimals. 
      The CST is coming up so I have to review this in my math class. My teacher says that there could be a lot of these questions on the CST. The CST is a really big test. Another reason that I have to review this math is just to know it. I need to know this because this goes all the way back to third grade. The CST will help me get into colleges and maybe even into better high schools. 

  I like to use a certain method for changing a fraction to a decimal. A lot of people use it. First, I divide the numerator by the Denominator. This method is really simple and easy. I started learning this in the fourth grade. This method is very easy and I think it is the best way to turn a fraction into a decimal. One example of this method is 25/100. All you do is divide and the answer should be 0.25 or .25. Another example is 10/100. Just Divide and the answer should be 0.10 or .10. Those examples are easy. There are other problems like this, but a little bit more difficult. They are not super hard like a math test or anything. I learned this method in fourth grade and in middle school. Everyone I know says that this is the best method to use including my teachers.

      Say you were going to a restaurant for a nice dinner with your family. You order and you start thinking of the bill. You start to think would is gong to be. There are many ways to determine how much the bill will be. Two ways are percent and ratio. Ratio, from what I know, tells something like and estimation to a couple of numbers. Another way is percentage. Both of these ways can help you determine how much the bill is. I have thought hard about this and and I think that both are useful, but ratio helps more. I have asked many friends, family, and a couple of teachers this question and I have received more answers that say ratio. 

     Finding the circumference of a circle with a 3 foot diameter is pretty easy if you know how to do the math. First you must find the radius of the circle then you multiply it with the diameter. It was Pi day last week and everything was about Pi. My math teacher even made us go outside and do an activity on how to find the circumference of Pi. He told step for step and then solved it. Then we went back inside and did more math stuff like problems. Everybody in my class knew what Pi was. Pi equals 3.14.  

  I know a couple of things about pi and why it is so special. Pi is a math term that is equal to 3.14 and is used in equations and most of any type of math. Another thing is that pi helps with real life situations too. I am learning this in math and my teacher says that there is still a lot to learn. I also know that pi comes from circles. This morning in my math class, we watched a video that was a commercial in the Superbowl. It was about a kid who asked a dad where babies came from and his dad made a story about how babies come from a planet and come to earth by penetrating the amnisphere. This commercial was related to pi a lot.
