Problem:

The national debt is a problem of which we are all subjected to. At birth it is said that we already owe money. Your task is to find a way to calculate how much does a child born in 2013 owes at the time of birth.

Information

Number of people: 10 millions

National debt:21,989 million

What you have to do:

You have to divide the number of people and national debt then we get the amount of money that a child owe when they born.

Operation:

21,989/ 10,000,000= 2198.9

My man Isaac Newton

So we had to watch a video named: My man Isaac Newton and what was our opinion about it.

Well I think this video has a point, Isaac Newton was and will always be a important scientific for us, because without him alot of stuffs wouldn't make sense for us, and thanks to him today we can unspderstand better how science works. I liked very much this video and I think you should watch it.

Problem:  

Richard was at the canyon and he shouted his name down the canyon, 8 seconds later he heard his echo. How deep is the canyon, Explain how you solved it.

Solution:

What I first did I look up the speed of the voice, that is 343.2  m\s 

Now what we have to do multiply it times 4, Why times 4? Because it last 4 seconds to go down and to come back up again.

   343.2 * 4 = 1372.8 

So the canyon is 1372.8 long.

Pre-Algebra:

Problem: 

Tyler and Christina are playing a game in which each player either wins, loses ot Draws (ties). The winner is awarded 5 points, and the loser loses  5 points. If it is a draw 0 points are awarded. For te first 8 rounds Tyler had the following results: lose, win, lose, win, win, lose , win ,draw. What was Christina's point total for the rounds? Explain how you did it.

win = 5 points
loose = -5 points
Draw =0 points


-Well first I divided the points between the two of them.

    Tyler                                                                                          Christina
lose = -5                                                                                    win =5
win = 5                                                                                      lose = -5
lose = -5                                                                                   win =5
win = 5                                                                                     lose = -5
win = 5                                                                                     lose = -5
lose = -5                                                                                   win =5
win= 5                                                                                      lose = -5
draw = 0                                                                                  draw =0

Now all we have to do is add and subtract the point for each of the players.

Tyler                                    Christina

Total points: 5                      Total points: -5

Christina total points is -5 (negative 5) so the winner is Tyler with the  diferrence of 5 points.

Differences of Math Now and Then

Differences of Math Now and Then

Well normally math has been a class that is boring for some people and for others it was complicated. Well since 5^th grade math gets complicated and it gets even more complicated when bigger, but Pre-Algebra for now all I have learn in 2 weeks have been easier than 6^th grade and 5^th. And something that helps us learn is the teacher that is very cool and interesting and he knows how to explain. But math will get more complicated over the years, because it normally does…

 6^th grade we learn about something you will have to use for more courses of math like 7^th grade 8^th grade etc. We learn basic things such as:

-Decimals

-Proportion 

-The start of Pre-Algebra

-Variables

-Units of the metric system

But now in 7^th grade we will learn new stuffs and practice the old stuffs, Math will always be there in our life even if we don’t notice it. So for now the stuffs we have learned in 7^th grade Pre-Algebra are pretty easy. I think is easy in its own way because they are, and because the teacher makes it easier for us.
