Well, this is my last Math Monday and blogging about it has actually helped me a whole lot. The main thing that I liked about it was that, Math Monday is a weekly thing. So I am like getting extra help each week, besides in my math class.
It also helped me review some things I had trouble on. For example, if I didn't remember a specific problem, then the math blogs would help me refresh them back into my mind. Blogging about explaining math with a piece of paper and a pencil or saying it. So typing about math was something pretty new. But I'm glad to say that I did because I learned so much.
So what if I worked in a restaurant. I was going to purchase food for the restaurant, and my only options to use were ratios or percentages. In my opinion, I would use percentages. I'd use percentages because for me, I understand percentages better than ratios. Like for example, say I am going to buy like ten pounds of ground beef
At first I thought Pi was just the ordinary food we eat, but it's not. Pi isn't just food, it's also numbers! I know if you didn't know that, I bet you're blown to pieces, but yes Pi includes thousands of numbers. I couldn't believe what was being told from the first day I found out but Pi starts with 3.141 and it keeps on going. I believe it doesn't stop, and that's why mathematicians are trying to find out. The real definition to Pi is the number π is a mathematical constant that is the ratio of a circle's circumference to its diameter, and is approximately equal to 3.14159. Yeah sounds pretty fancy don't you think?
I learned lots of things last semester in math class, but the main subject was integers. Integers was one if the hardest units in math, because I couldn't understand the negatives and the directions to go on a certain number. I didn't know what direction to go to when I found the sum of -23-(-12). After I told my math teacher, he taught me the ways. Whenever you are subtracting a negative number from a negative number the number is going to shrink but it may or may not be negative it just depends on the size of each negative number.
I found out that I had to go the negative side because the number wasn't big enough. When you are adding a negative number to a negative number the number is always going to stay negative and it is going to add up. So that means it is always going to the left which is the negative side of integers.
In this Math Monday blog, I am going to blog about square roots. And if you didn't know what square roots are, well they are numbers that produce a specified quantity when multiplied by itself. For example, 5^3 is 5x5x5, and the way you multiply it is multiplying the first two numbers, and in this case it would be 25, then you want to multiply 25x5.
The main reason for this blog is the naming of square roots. Well in my opinion I think square roots got its name by how there are a little number that's next to the base number, and to me that kind of reminds me of a little root.
Today is Math Monday and I am going to talk about one, specific lesson I have been doing in math class. I am in Pre-Algebra and in fifth period we have been learning about negative and positive integers and the absolute value. My teacher taught us when to add or subtract from a negative and when my classmates and I shouldn't. It's hard and I didn't understand it at first, but once you know what to do you'll get the hang of it.
For homework we solve about 20 questions mostly everyday. They're all easy but there's that one question you don't understand. So what you should do is look at all the other questions and compare it to that one question. It helps me a lot. So, there was a test last week and it was pretty easy. I only missed one, and that question was about absolute value. I knew what I did wrong, and I could've got it right.
So today my computer and math teacher asked me, "Why are there an infinate amount of numbers between zero and one. Well that is what i asked my fourth grade teacher. As I got older I found out that there are decimals and fractions between zero and one. Since there is a 1.5 which is one and one half, that can be the same between zero and one.
On an ruler the little dashes mean point one (.1) between zero and one. You can even change it to a fraction by adding a line and the number ten under the decimal. Then take erase the point.
Today's "Math Monday" and I am going to blog about how their is no division in an expression like "2x+16". The reason for this because you don't automatically divide, you first need to make a fraction instead of just dividing each side by two. When you make 2 and 16 into fractions by adding a dash and the number 2 under each number, you know want to divide. To do this your want to make the house you use in division, and remember the numerator is always in the house.
The denominator is always out of the house. If I use this method, it'll be very useful and faster than just dividing each side. This method would make my answer more accurate, so I'd have a better grade on my paper.
Everyone has their favorite math method they use to help solve math in a better and fast way. I have lots of methods I like to use but I am only going got say my top three. Well one of my favorite math methods are using exponents. If I see the a multiple number multiplying lots of times, I'd change it to an exponent. The reason why I'd do that is because it makes plenty of space.
The second method I would use for math would be focusing on reasoning. That means to write down ALL the possible ways to solve the answer, like I am doing right now. I use this because you can skip many steps and get the right answer. So you do solve a question with all the ways you know, and then compare all the answers. The last method out of my top three would be spending a lot of time on the topic I don't understand.
