How has writing about math helped you this year? Writing about math has helped me understand certain ways that math is solved. Sometimes, I wouldn't understand how a problem was solved, and writing about it made me understand how to solve it. There have been many math Mondays during the whole school year, but this will be me final one. All the writing we have done this year has helped me and my grade in math. 
       It has also helped me on a test when I might have not remembered, but then I did because I wrote that one blog post and I remember. If I wrote it, then of course I would remember. It hasn't just helped me with math, but with all my other subjects too. In the future, writing about certain topics will be required, and I think it's a good idea, because if you write about it, it helps you learn, or at least it helps me learn.

The hardest thing I had to learn in math all year was dealing with parabolas. Parabolas are lines that you have to learn how to solve using equations and they look like lines with a curb in the middle, or a turn. There is a certain formula you would use to find a parabola, and how to graph it. 
     To graph a parabola, you need an equation. That equation has to have an A, B, and C. After figuring out which is which, you plug those numbers in into other equations that help you find the axis of symmetry and points that connect the parabola. I don't know why I had trouble with this even though it looks pretty easy. All I had to do to understand everything about parabolas was just look at it another time and practice.

What are some connections between math and science? Math will always be a part of science. The question is, how are there or what are the connections between science and math. One way you know that math will always be a part of science because there are certain things you need equations to solve how old something is or how it was first formed.
     For example, the relative dating method is a way that you can find how old something is. In order to find how old it is, you have to use a special equation, just like the one in the relative dating method. There could also be another method for figuring out the speed of how rock change. For example, the four time periods. From before the dinosaurs live, to now.

What are negative numbers? Where do you find and use them in real life? Negative numbers are numbers that come before zero, and it could mean you owe something. Think about a bank account, if you have the money then you could take it out whenever you want. Then you decide to take out more money than you have, which takes you into the negatives. That means you now owe money to the bank.
     If you are trying to solve a math problem, you could easily find a lot of negative numbers there. For example, try solving an algebra equation, you could always find negatives there depending on the numbers. The negative sign is just like a minus sign. When you have a minus sign you subtract, but you could still stay in the positives. If you take more then you have then you will owe that.

Last Monday, I wrote about how you convert the fraction into a decimal, now it's the opposite. Converting a decimal into a fraction isn't any harder than converting a fraction into a decimal. If you have a decimal, for example, .3 you would easily be able to convert that because .3 is a tenth, and in the fraction it's three over ten. 
      Here is another example, except this one is using hundredths. So if you had .03 the answer in the fraction would be three over a hundredth. Each time you add a zero after the decimal, you add a zero to the denominator. That would mean if the decimal was .003, then when you add a zero then you would get the fraction of 3 over a thousandth.

How would you solve the problem above? In order to solve the problem you need to figure out what x is. You find x by getting 2x on one side. In order to get x on one side, you have to add 7. Whatever you do to one side you have to do to the other. So you add seven and your new equation is 2x=22. After that, you just have to divide 2 so you can get x by itself. So the answer would be 11, or x=11.
     That would be a method to use when you solving any kind of those types of problems. Wheather it has more than one x or not, it's pretty much the same thing. Here are the steps again: add seven so you can get x by itself, divide by two and get an answer of 11. The answer would only work for this problem, but the steps are pretty much the same.

What are two methods you can use in order to convert a fraction into a decimal? There are more than two methods to convert a fraction, but we are only looking for two. One way to convert a fraction is by dividing it by how it looks. For example, if you wanted to convert the fraction 4/5, you would divide 4 by 5. Then you would get the decimal form of that fraction.
     The other way to convert a fraction into a decimal is by knowing what the conversions already are. To do it the other way you would need to know how you could use the decimals to make the percentages of the fraction or the percentage. For example, say you got the answer of 4  divided by 5, whatever the answer is, it should be in decimal. Once that has happened, you would just add a percentage sign and you would get the percent.

What is a ratio? A ratio is something similar to a percentage but instead it look like a fraction. Percentages come from fractions so they relate very closely. The ratio can be formed in three different ways, like the fraction, with a decimal or just a plain number. A percentage is only a number which signifies how much of something is there or not there. 
     We came to choose out which would be better to deal with, ratio or a percentage? We would have to figure out which would be better to use when you're at a restaurant or at the food store buying food. At one of those moments I think that the percentage would be a better way of figuring out which one cost less and it could help you because if you had the ratio you could be confused on which way you want it to look. That way it's better to keep it simple and use a percentage.

How do you find the area of a circle with pi? You always have to measure the diameter or the distance on how long it is. From there you get the measurement and then you multiply it by pi and you get your answer. For example say you have a circle of about 3.25 inches in its diameter. You had to measure that in order to get  the inches and then you have to multiply it by pi in order to get the answer of 10.21. Of course, I rounded, but before we multiply we are going to have to round pi to 3.14 or you'll just get the longest of the numbers.
     Here is another example: If you have a circle of about 13 inches what would be the answer? Well all we would have to do is multiply 13 by 3.14, and we would get our answer of 40.82 inches in the circle's area. That is a simple easy way to find the area of a circle.

What are some things you should know about pi? Not pie as in the kind of eat but pi the one used in math. Pi is a symbol mostly everyone knows about, and there is competitions on Pi Day just to see who can memorize the most numbers of Pi. Pi is a number that goes on and on forever without stopping. All I know is that it starts out with 3.14159, usually the shortening for that number is 3.14 for in math problems you would use 3.14.
     There are some things that we could know more about Pi. Like how it's practically a number that repeats itself, because after a long set of numbers it''s like if the same numbers where there. Nobody knows for sure if anyone could memorize the whole number of pi, but that is why there are competitions to see who can memorize the most numbers of pi.
