This is our last math Monday that we will ever do. I'm happy this is our last time we are doing the math Monday.
A lot of the topics we talk about are confusing, or we didn't cover them yet. I am happy the school year is almost over too. These blogs are a little hard for me because math is definitely not my best subject. Math Mondays were probably my least favorite blog along with science solutions because a lot of the questions didn't really make sense. I don't think doing these blogs helped me very much overall. I wish that the common core didn't make us write about math like these blogs, because they are not fun. I knew that the policy is changing next year, and I just hope it changes for the better and makes math a little easier to understand.
In Math class we have learned more then I remember! But today I will be talking about one of the hardest concepts for me to learn & how I ended up learning it!
The topic I chose was Slope because because I definitely remember it being a hard subject for me to learn & it was a challenge. I ended up learning it from my brother because I just couldn't understand what my teacher was saying. This happened to many people in my class so I think it was the teachers fault, but anyways I learned from my brother who is in calculus & statistics and all the other advanced math in college. He is a very good teacher & a good student in math so whatever I need help on, he helps me all the time. Without him I would probably be failing mat right now & earlier in the year. I would have to say that slope was one of my most challenging things to overcome in math only for the reason that I couldn't understand it in school so I had to learn it outside of school which was a little tough.
Science & math are similar in a few ways.
Science is basically Math. Other then the experiments all you do is calculations. If you don't know how to do math or averaging or any of those simple skills, how would you conduct experiments? You wouldn't be able to & you wouldn't be able to solve the problem or prove the theory. Science is all math & it is only possible if you know certain math solutions. They are similar as well in what tools they use. Both science & math use calculators & tables to organize and help with their data. They both ave the same objective. Both Math & Science are trying to figure out a problem or prove a theory. As you can conclude from these statements math & science are very much alike and you wouldn't be able to have one without the other, and without these methods our world would be very different today.
Today I will be talking about negative numbers. Negative numbers are kind of self explanatory. It means that whichever number is below zero by that much. It is actually less then zero itself. So the larger the negative number, the smaller the number actually is, because the more below zero the less there really is. You know it is a negative number when there is a small minus symbol in front of it. like this -3 or -1348.
Negative numbers aren't used to much outside of math, but one example I see being used a lot is when working with temperature. When the temperature is so low it is below freezing it is usually below zero. Many places such as Antartica are always negative temperatures. Negative numbers are used in math a lot & when you multiply with a negative number the answer is always negative, and when you add two negatives together the answer is always positive. A simple rule to remember is that 2 negatives always make a positive. Negative numbers are a good thing to know, but they aren't used a ton in our daily life.
Today I will be talking about how to solve this problem.
The first stpe is to eliminate every thing but the variable. This is known as getting the variable by itself. SO you would add seven to the fifteen and to itself leaving you with 2x=22. Then you would divide 22 by 2 and get eleven. So then you would get x=11. So the answer is eleven. T
When you change a decimal to a fraction you put the number to the right of the decimal out of one hundred as shown: .25 = 25/100. If there is a whole number or a number to the left of the decimal you put that separate from the fraction or to the side as shown. 1/25 = 1 25/100
here are some examples:
4.98 = 4 98/100
2..00 = 2
.74 = 74/100
If the decimal has three spots on the left side of the decimal you would put that out of a thousand. as shown:
.876 = 876/1000
.765 = 765/1000
.321 = 321/1000
and more
& if the whole number is larger than a singe digit you can just leave it the same and put it at the end of the fraction as shown:
543.987= 543 987/1000
& so on
Changing a fraction to A decimal is super easy. Here are some examples.
1 1/2 = 1.50
1 2/10 = 1 .10
1/2= .5
& so on.
If there is a whole number in the fraction then you simply put that as one whole number so it would look like this. 1. The whole number would be before the decimal. Then depending on the fraction you have to multiply to find the decimal way, but I'll use a simple one for now such as 1/3 = .33. or 1/4= .25. Then you can add in the whole number such as 1 1/2 = 1.50 It is simple as that.
You use pi to help find the circumference or radius of a circle. If you wanted to find the circumference of a circle with the radius of 3 feet the steps are simple.
What I have learned so far in math is just to use 3.14, but I'm pretty sure in a few years in algebra & statistics I will be using more digits of Pi. So all you do is multiply 3.14 by three (or the radius of whatever the circle is). Then that is your answer.
