Sorry if this isn't the best blog because it's the first one of this year and it's the FIRST one I'VE ever done too.
Well, I think I should start talking about what happened today in class because that's what I'm supposed to be talking about but I don't seem to be doing that.
Okay, well, here it goes! =)
Well, today in class, we talked about who would be the first people to do the blog and what to do.
After that, we corrected the two worksheets we got the week before. One was on multiplying integers and the other was on dividing integers.
While we were correcting, Ms. Armstrong did a few sample questions. She gave a brief mesage about number patterns. It wasn't really something we should put in our binders or take notes about it but I think we might be talking about number patterns later on in the year.
Anywho, she explained the difference between brackets and parenthesis. Here are the notes about brackets and parenthesis :
* Brackets hold an integer together
example : (9)(-3) which means 9 x -3 ( nine times negative three )
* Parenthesis hold an operation inside
example : (9-3) which means 9 - 3 ( nine minus three )
* If there is no space in between variables/numbers, it means multiplication
example : (9x)(-3) ( nine times "x" times negative 3 )
We will be working more on brackets later on in the year. ( Hint Hint ) These notes down here about multiplying negative and positive integers :
* If you have an even number of negative integers, the answer will have a positive sign
example : (-5) (-3) (-7) (+1) (-3) = even number of negatives
ANSWER : +315
* If you have an odd number of negative integers, the answer will have a negative sign
example : (-5) (+3) (-7) (+1) (-3) = odd number of negatives
ANSWER : -315
That's basically all we talked about in class today. Hope that that was informative enough.
The next person who will be doing the Daily Blog for tomorrow will be Paris.
