Think aboout this, you have the slope of the line, but you may wnat to ask some quesrions to see if it is correct. Here is another problem, you dont know what questions to ask. Well, that is were this blog comes in. In this blog, I will be telling you some questions that have to do with the slope of the line. With these questions, you can use them to check your work, ask the teacher for help, or try to solve the problem. In the next paragraphs, you will learn some questions to ask for anyone of your slope questions.

To check your work, ask yourself this: if I plug in the slope where the variable is, will I get the same answer? To help you visualize this, just use the formula y= mx+b to help find the slope of a graph, or like I said before, to help check your homework, or anything that has to do with this. This can be a very helpful formula. This equation will help you with everything math, especially Algebra! I am very glad that we are learning this now, so that we know how to do this we will already know how to solve it. I hope that you have learned a lot more than you did before! Until next time!

     Do you know what Pi is, here is a hint not the dessert pie. Pi is a mathematical term. Pi is a very long number. The numbers that Pi is most common for if 3.14. Pi day is almost here as well. Pi day is on March 14. This is pretty funny, because March is the third month and the day number of the day is the 14th. My Pre-Algebra teacher, Mr. Dorman, love Pi. He loves anything to do with Pi. This year he is going to do fun activities on Pi day. He can not wait until it is hear. Pi is not only used in math, it can also be used in science  Pi looks like two parallel lines with a little squiggly line on top. It is a pretty basic shape.

     Some people like Pi and others just like real pie. Now I am going to write to you some numbers of Pi. Here it goes:

     Todays blog will be about the research of a 12- pack Mountain Dew box versus a 33.8 oz liter of Mountain Dew, with the question of which is a greater buy. If you do not know what Mountain Dew is, it is a soft soda drink, that has a lot of sugar in it. If you went to the store to buy a 12 pack Mountain Dew box it would be about 7 dollars. If you bought a 33.8 liter bottle, it would be about 2 dollars. To find the better deal, you have to first find out how much money is a can of soda in the 12 pack box. To do that, you need to divide 12 by 7. You would end up with a decimal answer,the answer would be about 58 cents for each can, and each can has about 12 ounces. Now, for the liter one, it is 33.8 ounce, for 2 dollars. If you double how many ounces sodas you want from the 12 pack, you would get 24 ounces for about 1.16. If you add 12 more ounces, it would be 36 ounces for 1.74 dollars. The better deal is the twelve pack for 7 dollars, because it gives you more ounces for you dollar.

 In conclusion, the better buy would be the 12 pack for 7 dollars. If you really do the math, you would see why the 12 pack is a better deal. This is an informative blog about which is the better buy between a 33.8 ounce or a 12 pack of Mountain Dew. It also really depends on if you plan to serve soda to more than 12 people, because it may also cost a lot of money. For this case, the winner is the 12 pack of soda.
 
     Today is Math Monday. In this blog I will be blogging about the hardest lesson in math that I have done. The hardest lesson for me was combining like terms. This was hard for me, because I was getting confused on which term you add together or subtract. This is what this problem looks like -2x+5-(-2). The first step would be to add or subtract all of the whole by them selves numbers. In this case 5 and -2, you would subtract the 5 and -2. That would be 3. Then, since there is not any number like 2x, you would just leave it alone, so the awnser would be 2x+3. After a while, I kind of understanded this lesson much better.

   The key to understanding something is to really pay attention to it. When I finally decided to pay attention to it it made more sense. The more I payed attention to this, I was able to make a connection as to how to solve the problem. Sometimes we tend to shutdown and stress out if we don't understand how to solve a problem, but then I relize to take a deep breath and start all over from the first step. Eventually that little step leads me to solving the problem. Solving a math problem is a proscess that unfourtunatly, if you don't understand it from the start you have to start all over.
 
     Today is Math Monday. In this blog, I will be giving two helpful reasons where to use phythagoriam theorem. Pythagorimu theorem is when you have two sides of a triangle and your trying to find the other side, the solution to that would be A^2+b^ 2 would equal C^2. Here is a solution were you might have to use it. Say that you want to find out which path to grandmas house would be faster. There's one were you have to cross the lake and over two rocks,and there's another path were you would cross over the sand, and over a log. When you cross the sand it is two feet steps for second, and when you row the lake it takes 10 minutes which one is faster. This would be another great time to find pythagorium theorem. Another reason is you want to know how big two squares need to be to fill up a big square. So you know that the volume in one square will equal 3 and the big square will equal 7, so this is another reason you might be able to use phythagorium theorem.

     This is what we are currently learning in Mr. Dormans Pre-Algebra class. It is very very very easy if you know how to do exponents and root squares. Anybody can pick this up and earn it fast.
 
Today is Math Monday. In this blog, I will be blogging about what are square roots, and why they are called that. Square roots is like area and perimeter. If the square root is 7, then that means 7x7 equal 49, so that is the number you are diving it by. The answer in this case would be 7. This math lesson is named "square roots", because whatever you're diving by is half of that number. Square roots come in handy if you need to find the perimeter of the square. This a constant thing people use to help idenify what it is they have to know. I think that this is also very useful for carpenters, and construction workers. Math will go were ever you go, so these lessons are really important. The square root of 64 would be 8, because 8 x 8 equals 64. Here is another example, the square root of 80, would be between 8 and 9. If it is not a perfect square, then you have to list and estimate what two numbers it would be between. 

This is how you know how to find the square root of something. It is very simple to do. This is what we are currently learning in Mr. Dorman's Pre-Algebra class. I hope that you find it easy to find the square roots, like I found it easy to.
 
           Todays blog will be about why 5^-2 equals 1/25. This was the math lesson that we had last week. The reason why this is 1/25 is because the base 5 has to be multiplied by ^-2, so first step is 5^-2. That would be -25. The second step is that when you are changing this to a fraction there is always a one for the numeration.  So it would now look like this 1/-25. Heres the next step what ever turns to a fraction, has to turn positive. That means that -25 has to be positive 25. The answer now would be 1/25. That is how you get the answer to that.

At first, I did not really get this math lesson. The reason on how I knew how to do it was I looked for the problem. Once I got the awnser, I would plug it back in the problem. That is one good stradege to use when your are not sure in it is right or not. After really paying attention to this I got it. I learned how to do this problem. This is just like fivth grade exponents, but a little bit challenging.

This was our math lesson. After practice, and practice, I finally got this problem,and know how to do it.
 
                Todays blog post wil be about what I know about exponents. Exponents make a number pharse smaller so insted of like this 7x7x7x7x7 is would look like this 75. The five would represtent that there are five times that number. Exponents are really easy. They just make a long math equation like 5x5x5x5x5 into 55. This is kind of like a review of sixth grade. This will be my math lesson this week and it will proably get a little harder. I think that this is a really easy math lesson. It just makes life a little bit more easier, when doing exponents.

                    If you still kind of don't really get exponets reasearch it to get a better picture. All it really is just making a longer problem into a shorter one. To get the awnser all you do is multiply the problem. So to awnser 7x7x7x7x7 you would just multiply it. I hope that you have learned a little bit more about exponents. This type of math isn't really that hard it is very easy for me, and I hope it would be easy for you.


          
 
                 Today is Math Monday. This blog will be about a game that we have played for math. It is a very educational game. It is very simple, all you have to do is subtract the big number by the little one to get the answer. This is an online educational math game. It is called Diffy. You can subtract by integers, fractions, while numbers, and money. This is a very simple game that only requires thinking. For this game, it has about five levels. They are very easy levels. The object of this game is to fill in the blank spots in the diamond by just subtracting the numbers. It makes you a faster thinker and solver. This game is also good if you are bored and have nothing else to do. Diffy tries to challenge you, by making you solve problems faster than you normally solve them.

             I strongly reccomend Diffy, because it helps you learn a lot more faster. You will get good at it every time you play it. It is really easy all you do is subtract. This will help you be a faster math learner. This is the key to mental math. Here is the link, click here. You will know mental math more easier and faster, like I said before. If you really want to know subtraction more faster than normal, check this game out. If you play it for at least three times a day you will know this more faster, like I said before.
 
               Todays blog post will be about why when you graph an inequality such as: <, >, <, and >. , you have to either put a closed dot or an open one. You only put an open dot when you don't have a line underneath the greater than or less than sign. You put a closed dot with the signs that have a line underneath  We do this so that we can tell the signs apart if they are different signs. You have to do this if you want everybody to see your point and were its located and if it is a less than or equal to or if it is a greater than or equal to. This is just something that you have to do in order to tell these signs:  <, >, <, and > apart from which way you are going.  This is the current lesson that we are learning in my Pre-Algebra class. It is not that hard if you know which inequality that you are using it is basically like greater than and less than, or >, <, but in a little bit harder way. You can also use these to form a problem like v+5>12 You would then subtract five from both sides. The problem would look like this 7v>7. All you do next is to do the opposite that it is telling you so that the number could cancel out, so it would look like this v=1. That is all that you do to solve a problem with inequalities, and this is how to tell them apart with a different way of graphing it.

                I hope that you learned a little bit more about this topic for more information click here to go to a page in my website that explains more about this topic. This is really helpful to know, and I'm sure that it will come back someday, and you will know how to do it.
