Math and science are used together because when you are doing science you sometimes need to use math to help you with what you are learning. For example in class we were doing this activity where we learn what length of a mirror we will have to buy so that we are able to see ourselves completely. This activity showed us how reflection of the mirror makes you bigger or smaller when you get closer  or farther. We used math in this activity to graph the activity that we doing. When we graphed the activity we had to calculate a ratio to see what kind of size mirror we will have to buy if we were to buy a mirror. With our calculations we found out that if we were to buy a mirror that we could see ourselves from top to bottom the mirror will have to be half our size. That is what math can help learn when you use it in science.
When do we see negative numbers? We would of course see them on calculators, math class, and maybe even on math topic restaurants but the place where you would see them is when you solve a problem like what is 2-4 and the answer would be of course negative 2. That's way that you solve that problem is by first learning the number line including the negative numbers. So for example if right now I were looking at a number line that goes form -4 to 4 I would see it like this: -4, -3, -2, -1, 0, 1, 2, 3, 4, and of course it continues.
Negative numbers are very hard to find in everyday places because how many times a year are you going to run into a store or person or anything like that, that is going to have a bunch of negative numbers. Most of the time negative numbers are usually in math problems that can help you with everyday things. Some of the everyday things that negative numbers can solve for you in science and many of other things.
The first step you will have to do to solve the problem 2x-7=15 is by adding 7 to 15. Think of this, we are working our self backwords in the problem and the last thing that we would do in the problem is minus the seven. So lets continue with the equation. Next we will have to find how much times 2 can go into the sum of 7+15 which would be the answer 11. the answer to the problem is 11. To check if the answer to this problem is correct solve the problem again but this time adding in the number replacement of the variable(in other words the answer you got with the problem you just solved). This is how you would solve equations similar to this one.
I would use a ratio instead of a percentage because finding the ratio of the restaurant would be easier than finding the percentage. When you find the percentage you have to a lot more work when you can find the difference between the two choices to choose from in the choices for purchasing food for use in a restaurant. First of all I would like to find the exact amount which is the same as finding the difference than just finding a percentage that will give me an idea of how much there is but in a simplified way when I am trying to find the exact and the exact is when I find a ratio which can give me a clear and straight out fact that one is bigger than the other amount.
I would also choose finding the percentage , but when you find the ratio to the problem it tells you a clear answer to the problem you are going to solve. I would also use percentages for when I 'm trying to solve a problem like this but that would be in things like if I were trying to find the amount of pizza I ate with my friends of something like that, but most likely I would just use a ratio to find out what would be better to use in planning purchasing of food for use in a restaurant.




Pi everyone! Sorry I just wanted to put something cheesy into the day. Well pi is the way to find the area of a circle. And that is useful for things like trying to find the area of a pizza to find how much pizza or something random like that. One thing that you should mainly know is HOW to find the area of a circle. To find the area of a circle is by timing the diameter of the circle with the pi which is 3.14. It can also referred as 27/3. When you have done that you will have to cheer and dance because you have found the area of a circle. Finding the area of a circle without pi would be really difficult pi really helps a lot during math.
Pi is very long because it is a rational number. Here is an example for you to get an idea how long it is: 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899 and so on. Some people know only 3.14 and some people know a thousand more after 3.14 but, all I know is that I only know what I have to know and that is 3.14 itself and when it is translated into a fraction(27/3).
Square roots are when there is numbers like 2 times 2 or 15 times 15 and so on. The one that I don't like about square roots my teacher gives us big numbers like 400. The answer to that would be 20. the ones that don't have a square root are the ones that are between two square roots. For example is maybe what two square roots is 15 between and the answer would be 12 and 14. That isn't so hard is it? Lets see if there is something that is more of a challenge. The number 19 would be between two square roots 16 which has the square root 8 and also between 25. this are some of the example of things that I did as homework about exponents.
Negative exponents are not that simple to solve but I'll tell you the truth it might be hard at first to understand but this how it goes. The way that you try to find an answer like 3 exponent -8 is that you first try flip it over to be now 1/3 exponent 8. the fact that there is now  fraction in the problem you will now have to solve the problem of 3 exponent 8. There the answer would be 1/24. That wasn't so hard was it?
     Well when I was little my mom was trying to help me to learn to round number and I didn't know how to but I did know how to do the basics for example that anything above is going to be the next set of numbers. Well when my wants to teach me something she teaches me until I know the problem to my  problem. We even stood like until ten o'clock to find out how to teach me how to do the easiest thing on earth. Once I knew how to round numbers I couldn't believe that was  so easy. That was a little too ridiculous to actually handle as the thing that I couldn't figure out very quickly as I thought I  would. 
     Another thing that actually had happened recently is that well we were learning how to do this problem that you had to well find the answer to a problem that had a bunch of that I couldn't understand. But mainly I'm just saying when you need to learn something new you have to work at it until you know it.
Exponents are very fun to solve in math problems. I don't know if they ever show them anywhere else. My teacher said to try to find them around. But I can't. Where can you find exponents at. The only place I know where there is exponents is inside my math book which I don't think that is very smart place to find the exponents. Who knows where exponents could be seen around. do you guys know any place where there is any exponents at?
In math we were assigned to do this game and had to finish at least three levels of the game and well just saying the game was very hard to tell the truth. In  my first levels it was kind of easy to do. I didn`t think it was that hard to actually just find out the difference between negatives so I moved on to doing money. It was still not of much of a challenge. There is something about this game that is well special,about it. When you play the game you will have to finish the whole circle to finish the whole level. I didn' have time to do the third, but I was able to see how this game taught how to get faster at doing subtracting money, decimals, and last of all integers. I can tell that this game is going to help with my way of doing things like subtracting money from my future bank account.
