Okay so first off I would like to say a few things before hand. One is that I, Jessica am the scribe for today and that I am sorry that this wasn't done earlier. I am really stupid for not remembering it but the truth is I am surprise I am doing it now. That is all.
Okay so today in class if I remember correctly we corrected homework and talked about the multiplying rule question. Okay so the rule which will be referred to as 'Ron's Rule' is what I will be talking about.
Ron's Rule, and I quote what was on the smart board today in class, is 'Multiplying an odd number of negative integers make a negative product'. It is that simple but I will try to explain a bit more.
So lets make a small chart to make things easier.
(-1)(-1) = (+1)
(-1)(-1)(-1) = (-1)
(-1)(-1)(-1)(-1) = (+1)
(-1)(-1)(-1)(-1)(-1) = (-1)
Okay so the ones in Italic on the chart are the groups with the odd amounts of negative integers. These all end up making a negative product. This is what Ron's Rule shows us. It even works if you have a Positive integer in front as long as there is an odd amount of negative integers.
Well that is all for today. Is it still today? I think so. I'm half dead(=asleep) right now. Oh and again. I am sorry for doing this so late. I have to start using me agenda again. Well, I have to go but for that I get to pick the next scribe. hehe. I choose........ Tiara. Mostly because I can't think any more.
