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.
To calcukate this we have to look which is the national debt and the number of habitants
National debt is: 21,989
Habitants: 10 millions

 So as we wanna know how much 1 person owes at birth we have to divide it
21,989 divided by 10,000,000 is 9198.9

So a child owes 9,198.9. 

My Man , Isaac Newton.

My opinions on this video were really quick, all that man said is true. I admire
Isaac Newton for his intelligence and how he said. Isaac Newton is such an important person tu admire, starting of who would ever think that all the colors of the rainbow would be white. Just a mind like him would have tought of that and obviously proove it . I really see Isaac Newton as one of the hugest historical Icons in the whole story of Earth, definetly, my man, Isaac Newton.

Why did Kevin Joa felt of the chair when the teacher pulled the chair?

Because kevin joa wasnt expecting it so he didnt apply any force that affected the gravity.

Physical Science:

Problem: Richard was at the canyon and shouted his name down the canyon, 8 seconds later he heard his echo. How deep is the canyon? 

How to Solve it:

First of all we search for the speed of sound. 

Speed of sound = 343.2 meters per sec.

So as what we have to do is calculate the distance (depth which is the distance from the canyon from the top to the bottom) , The fomula to calculate distance is D= S * T ( distance equals to speed tmultiplyed by time) .

 In this case the Speed is 343.2 and the time 8 secs.
So we multiply 343.2 * 8 (speed multiplyed by time) 

343.2 * 8 = 2745.6 

Answer: The canyon's depth was of 2745.6 m

Pre-Algrebra

Problem:
Tyler and Christina are playing a game in which each player either wins, loses or draws. The winner is awarded with 5 points, and the loser loses  5 points. If it is a draw 0 points are awarded. For the 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?

How to Solve: So first i made a chart diving Tylers and Christina's Ponits :

                       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
Draws : 0	Draws : 0

You can delete the Draws section if you want for you not to get confused. But you can also leave it but its 0, it dosent represent nothing.

So after you make the char all you have to do is add them. An easy way to add the is adding the positives and then the negatives i mean in diferent calculations. 

So we will have:

Tyler:                                                                      Cristina:

A) -5 + -5 + -5  = -15                                                           A) -5+ -5+ -5+ -5 = -20

B) 5+5+5+5 = 20                                                                    B) 5+5+5 = 15

C) 20+ (-15) = 5                                                                       C) 15+ (-20) = -5

Answer: So Tyler got 5 pts and Cristina -5 which makes Tyler the winner for 5 pts. 

Changes of math before and after

Math has been better so far, I really prefer pre –algebra. Classes are more fun and the teacher really improves it.  It’s easier well from all we have done it seems easier.  In 6^th grade we did a lot with more numbers more boring calculations and a lot of geometric. Now I love my clasess. Last year we had lots of homeworks and it was boring.

Something that we had in common was proportions and PEMDAS.  So if you are going to 7^th grade be prepared do all of your homeworks, study, if you don’t understand ASK that’s the key word. I really like my classes and we are giving fun topics that are really difficult.

 In 7^th we are gonna give some new topics that are really difficult since other people and classes had told me , we are going to learn new things based on all things like proportions and PEMDAS. We are probably using all type of operations and variables which we had practiced with Teacher Yulissa and We are using this year with Teacher Eladio.

So this first week has been very good, ive been doing well and i like it, we have done many classes but they have been easy i really like them so here ill be posting all my homeworks enjoyy!
