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!!

    Heey Jay, heres my comment. You did a very good job. but, on the "integer rule" part. Its a little confusing, when you read the rules it looks like its in one sentence. And you did a very good job on one picture but thats your only picture. You should've put pictures on most of the questions. Im not sure, but i think your also suppose to include the questions that we had talked about in class. And yeah, other than that it was really awesome (: oh, add more colours on the fonts.

    Hi jay ! Well, I think your post was really nice. You put like math words and your made it sound so smart. Um, I think when you are listing the rules your supposed to do to solve the integer question properly you should put it like this :
    1) type the rule and enter
    2) type the rule and enter
    3) type the rule and enter
    I think its better to do it like that because its easier to read. I think thats all you have to do next time .. OH WAIT , make it more colourful :D Well , yours was great that so GOOD JOB!
