journal entry: today in class we learned about the property of -1. this means that when you multiply any number by -1, you just rewrite the negative sign in front of the number. for example, 2*-1=-2. we also learned about the inverse property of multiplication, which is similar to the distributive property. an example is, -(3+2)= -3-2. all you have to do is distribute the negative sign to the 3 and the 2.
I deleted one of the journal entries because I should not be the topic. What you learned or discovered about the algebra topic is what you should be writing about. Summarize and draw a conclusion or tell something interesting about the lesson.
@Kamron I like it. You summarize and use examples but leave room for someone to object and add more.
Today we learned about the inverse property of a sum. The vocabulary we learned was the property of -1 and inverse of a sum. The property of -1 means that -1*x=-x.Inverse of a sum is that -(a+b)=-a-b. It is basically the distributive property.
Journal entry: Today in math we learned about the property of negative 1. The property of negative 1 is when you multiply something by negative 1, it turns into the opposite of what it was. For example, -1x=-x, or -1(-x)=x. We also learned about the inverse sum property. This property is similar to the distributive property,but instead of distributing numbers, you distribute the negative sign. Example, -(a+b)=-a-b, or -(-a+b)=a-b.
wait so are we all supposed to put our journal entrys? because i heard that it was whoever the people choose to go next, gets to post their journal entry
Today's lesson was about the Property of -1. The property of -1 is... -1 times a number equals that number but negative. I also learned how to distribute a negative sign. For example: 20*-1=-20 and 5y-(9z -7y) = 5y-9z +7y= 12y -9z
journal entry 9/23/10 property of -1 and inverse of a sum property were the two vocab words for today. property of -1 means when multiplying a positive number by -1, write a negative sign infront of the answer.. (example:-1*7=-7) inverse of a sum property is like chopping the problem and putting a negative sign on both sides.. i think. (example:-(5+8)=-5+(-8))
Journal Entry: Today, I learned the Property of -1. This means that when you multiply any number by a negative number, the product is negative. Also, I learned the inverse property of mulitplication. An example would be: -(a+b). The rule is simple. All you need to do is distribute. In this case, just distribute a negative sign to both variables.
today in class we learned about the inverse of a sum property and the property of -1. the inverse of a sum property is when you distribute a negative sign to each of the #'s inside of a set of parentheses. an example is -(4+3)=-4-3. the property of -1 is simply when you multiply something by -1. for example; 4* (-1)=-4.
It also seems that while the questions are being answered, I will reiterate some of the answers. I do not know who said I give tests every Friday, but they're wrong. That's an English thing. Lesson Check 6B does follow 6A, so everyone is suppose to be studying for that which IS tomorrow. The Chapter 2 Test being next Wednesday was also correct which was also posted on the blog at the end of chapter 1. Thank you to everyone who answered each of these questions correctly. Oh yeah! Good job remembering the airlines we would be taking if the prices remain where they are.
Oh and btw Eric and Sean for picking the people to write the journal i think the TAs should only pick the people who are in their own period,not doing other periods..... therefore the other TAs can have some fun too :]
@natasha I think it's easier if just we pick it because there is already a "system" type thingy. Also Taking the board off and on could be distracting, along with the different handwriting. But I guess we could figure something out.

For the D.C. trip, could I go next year when I'm an eighth grader?
you cam go, but only if they do it next year.

I have stacked the study guides from order of period and there should be a certain amount in each pile!

hey do we have a test tommorow?
hey mr.Gerson i wanted to know what day are you going to D.C. if you have 20 kids to go?
do we have a test tomorrow!!!
ya we have a test every friday i just found that out.
r u sure
no the test is next week we do have a lesson check thou
Whose journal entry did you delete someone from my period?
well he said that we are going to have a test every week
i asked mr.gerson during class and if we had a test he wud hav wrote that in his blog
ok nvm then people told me that we have a test every friday
to see tabs do u have to have a blogger account
do we really have a test tomorrow
no
hey can someone help me with number 15 on page 96 please

ex. 18*-1=-18 and -(3x+2y)=-3x-2y
You have a lesson check tomorrow i think. Because you guys took lesson check 6A today and you should take lesson check 6B tomorrow
Thank Andrew :D
When do we have the chapter test??
I think it is this coming Wednesday. I am not sure though

no only the people that he told in his class
is the textbook online
@ Gilbert, no some people told me if you search it on the internet the pages will come up.
Mr.Gerson told us that we're supposed to keep out books at home until June...
Journal Entries (only the ones chosen) need to be posted on this blog. So far:
Period 2:
Period 3: Kamron S. David S.
Period 4: Paige H.
Period 5:
Period 6:
There is no textbook online.

@ Eric
The ones that are blank are the ones that need to be posted right?

Mr.Gerson I gave her the notes like you wanted me to
Mr. Gerson do you know what airline we will be using for the D.C. trip
its united there and contential on the way back

David, could you please note what period you are in? Thanks. :)
Looking good.

@ Eric
ok, just wondering (:
if i was absent today what do i do with my hw i did yesterday? and do i do the hw tonight to turn in tomorrow?
Oh and btw Eric and Sean for picking the people to write the journal i think the TAs should only pick the people who are in their own period,not doing other periods..... therefore the other TAs can have some fun too :]
Some people still have to write in their journal entry
looks like per 5 wasn't paying attention or wasn't informed

@Sean choose another picture for yourself. That picture could be misinterpreted as a drink for someone over 21 years old. Thanks.
