In class we did something new, we made a book. The Book we made kind of looked like this...

In this book, we learned how to multiply integers. There was two examples that Mr.Harbeck and Mr.Backe showed us. The first example was under square one(++)...
Now, do you know how to answer this question? Well, just in case, here's one thing you should remember:
  • When two brackets touch you should always multiply

  • For this question, it's two groups of three

After you've done everything in the book I have just said it should look like this...

The second example Mr.Harbeck and Mr.Backe showed us was in square 2(-+) and the question was...




Now, do you know how to answer this kind of question? Well i'll show you how to do it. Since you've already seen the first example you should already know that when two brackets touch you always multiply right? Well this has the same rule but there is an added rule. First in (-2)(+3) the "-" means remove and the "2" means two groups and the"3" means of positive 3. So altogether it's remove two groups of positive three. So it should look like this...


And after you've done all of this the book should now look like this...


Now after you've done this there was homework, but it's fairly simple. All you have to do is create two other questions for (++) and(-+) but they don't they have to be hard. Just make questions that can be answered using the rules i talked about.

I think I made a few mistakes in my post so if you see any please leave a comment so I can fix it.


The next scribe poster is going to be one my buddies! So i'll choose....Patrick! Purple...I know right? His favorite colour :P

Today we learned about square brackets, and how to answer an integer question including them.
Here is an example of a square bracket integer question looks like:






Now how do we answer a question like this? Well, here are some things to remember:
1)Always answer the question in the brackets first
2)There should only be 1 integer in the brackets when you finish a question
3)If there are any subtraction signs to convert, convert them AFTER you answer the question in the brackets.

Here is how this question is answered:















Here is another example of a square bracket integer question:






This seems to look a bit more challenging, doesn't it? Okay well here's how to answer this question:
















Homework:
For homework we had to do part four in the green booklet (answers and work in notebook). Here are one of the questions from part four:













Another thing we had to do for homework was to do all of page 12 and pick any of the 10 questions to change them into standard form in our notebook. Here is an example of what to write in our notebook:









Okay so that's what we did today! If you guys see any errors, just let me know my commenting. I'll fix it (:

The next scribe poster I choose is .. MARC!

Today in Mr. Harbeck's class we got a new seating plan he drew our names by random and we got to sit where ever he showed us.

Now we get to the math for today, we had to do our green booklet that Mr. Harbeck gave us about 1 week ago and we had to do some parts 2 and part 3 on the next page.

We had to do learn Standard form in Integers rule and there are only 3 so here they are:

1) Never Subtract(add the opposite)
2)Regroup and Re-write
3)Have (1 +) and have (1 -)

That means in the end before you get the total you should have 1 group of positive integers and 1 group of negative integers.

Now we have our homework for today we did some of Part 2 and do the odds and Part 3 which is on the next page of the booklet. Now here are 2 questions on part 2 and 2 questions on part 3, here is part 2:

Question 3 on part 2:

8-(-4)+7-(-2)=
this is where the rules kick in to see if you are doing the process right:

So for question 3 Part 2 the answer is 21 now here is another question
Question #5 in part 2 it is:
12-(-3)+6-9
if you re-write that it should look like this:
12+(+3)+6-9=
12+3+6-9=
21-9=12
so 12 is the answer for question # 5 if you already did that question.

Now this brings us to part 3 it is a lot more confusing but its very easy if you do your steps correct, I'm going to do question 2 and question 10 so here is question #2

Question 2 in part 3 it is:

(8-11)-(4-5)=
(-3)+(-1) re-written with brackets
-3-1 re-written with no brackets
The answer is -4 on part 3 question number 2 okay now for the last question, question #10 and it looks like this:

Question 10 part 3 it is

-(-2+8)+(-3-4)=
+(+10)+(-7) with brackets
10-7 with no brackets and it equals 3
so the answer to number 10 on part 3 is 3. So that was for homework just the green booklet and also the is a quiz on Thursday about this I think so you better be prepared!!

MEAN


  • the sum of all data in a set of data
  • divided by the number of numbers in the set of data
  • the average of a set of data

3,4,5,6,7,9.10,11 (3+4+5+6+7+9+10+11) /8= 6.875

the mean is 6.875

MEDIAN

  • the middle number in a set of data

1,2,(4),5,6

  • (4) is the median in this set of data

MODE

  • the most frequent occuring numbers in a set of data
  • if there are no most ocurring numbers there is no mode

6,6,6,6,6,6,6,6,6,6,6,6,6,9,13,13,15,19,22,22,22,22,22,23, in this set of

data (6) is the mode.

1,2,3,4,5,6 in this set of data there is no mode

RANGE

  • the range is the highest value number subtracted from the lowest value number.
  • there is always a RANGE in a set of data.
  • second easiest

1,3,6,8, 9,10 1-10=9 the range is 9


zachs integer story

I only have $5.00! I want to go buy some candy at Ashcroft. Candy bags are one dollar each and the large keys are one dollar each. I want to buy one bag of candy and one key. Then I see a Red bull in the refridgearator for $2.00 and a Rockstar for $2.00. I put them all on the counter.



$ 1.00 + $ 1.00 + $2.00 + $2.00 = $6.00
I OWE $1.00
- $1.00
I'm not able to buy the candy because I don't have enough money. It's all because of (+1) + (+1) + (+2) + (+2) = (+6). Now I have to go home to get more money. As I walk home I find a looney on the side walk. Now I have $5.00. Then a bird swoops down and grabs it. now I have $4.00.

$1:00 (+1) + (-1)= 0

I hate zero pairs! I was almost at $6.00. As I walk home

I will start by saying that today was a pretty easy math class but there was one main thing that I want to talk about. In class we learned how to do a math Question with out the training wheels. In the green book question two is a perfect example of this. The question is -4-3. To find the answer it helps if you say it like this, negative four and negative three. The second step is to get rid of the and and add a plus. -4+-3 is easy to find out but if you want you can add brackets. (-4)+(-3). The answer is -7.







The homework for today is in the green booklet all of part one and all the even Questions on part two.
