Which one would you choose a 12 pack of Mountain Dew or a 1 liter. This ordeal can be conquered if you use common sense and math to help you. A 12 pack of Mountain Dew costs $12.99.
A liter costs $1.50. First you have to use common sense to find out whats in you pocket. You find that you only have so much to spend you should just go with the liter. You have a lot of money you should buy the 12 pack.
Last semester in math I remember the most was scientific notation. It was something new for me. It was kind of hard at first but when I got used to it. We had to move the decimal behind the first 2 numbers. We had to get rid of the zeros that came behind the last of the numbers.
Next we had to multiply the number that has the decimal in it by 10 and power it by how many times we had to move the decimal back to its original spot. For example: 235000000 move the decimal behind the two.
One year in math I had a pretty difficult time in math. The subject was decimals. The teacher taught it pretty well, but that day I couldn't listen very well because the person next to me would not stop talking. The teacher finally moved him, and I still couldn't listen. The teacher wondered why I wasn't getting it, so she put me in a group that could really help. They made it better, but still confusing.
The teacher finally put me in her extra help group, and it really helped. That week was hard, but it was very rewarding because through my struggle I learned a lot. He finally stopped talking, and I never needed that teachers help for Decimals. That teacher was so proud of me. From then on out I always told the person next to me to stop talking if the teacher was explaining something.
Have you ever wondered why a positive number not equal to zero is actually less than 1 but not negative? For example, 5 to the negative second power is equal to 1/25. I think it is negative because the negative power makes the number go to its reciprocal. Ex. 5 to the negative second power would be 1/5 to the second power. After the base changes to the reciprocal the exponent changes to a positive. Then you can multiply 1/5 to the second power. It comes out to be 1/25.
Have you ever heard of exponets. Well I have and I'm going to tell you where I've seen them and where might they be use ful to me. I have seen exponets before and they where very easy to do because I barley learned them. I also saw them again in 6th grade because my teacher was getting us ready for 7th grade.
I learned that they would be usefull to me when I have to multiply the same number many times and it would take up less space on the page or book.I also know that exponets help comstuction workers.
Mr. Kimbley assigned us a game and it was a very hard game and I learned some more things about doing math in my head like I'm not always right and that it's really hard to do. So I played the integers level and I found out that I need to work on that level so I will start working on that.
I also learned in the Fractions that I need to work on that. I couldn't add 1/2 and 2/3 in my head so I tried to bring out the scratch paper, but my mom didn't let me. She actually liked that game so now she's going to show it to all my old teachers. I also played the decimals too. It was very fun.
Have you ever wondered why when you graph inequalities you either open the circle or close the circle? Wel, I have the answer.You close the circle when you have the signs: less than or equal to and greater than or equal to. You close the circle because the everything is included. When you open the circle its because you aren't including the number below the graph.
Today in math I learned how to take a decimal that goes on forever and make it an equivalent fraction. Ms. Pope taught us a great shortcut that tells us to find out how far the numbers are behind the decimal. Then put subtract one. Then make that the denominator. Ms.Pope taught us very well but, it took everyone till the second problem to get the whole method, including me. I really like math and it just gets easier as we go on.
I think that the denominator gets bigger, and the decimal gets smaller because the decimals are not whole numbers. Also, because the denominator may need to be reduced more. Just like 1/4 is .25, or 1/8 is .125. Finally because the denominator is divided by the top number and that is usually smaller that the denominator. So now you know why the decimal gets smaller when the denominator gets larger.
Have you ever wondered why there is an infinite amount of numbers inbetween 1 and 0. Well I can tell you.
There is an infinite amount of numbers between 1and 0 because there are decimals and fractions between every number. Also because the numbers never stop like infinity and. My mom says that's the only reason that there is an infinite amount of numbers between 1 and 0. Here are some examples: .1 .2 .3 .4 ect. There are more but it would take forever and a day.
