Yesterday (Nov. 5th) we talked about each quadrant having 2 operations such as quadrant 1 with + and +. These are integers. Mr. Backe gave us questions yesterday and we all solved them in quadrant 1 and 2. For example, in quadrant 2, the question was (-2)(+3). We didn't see any signs of operations, but we remembered that last year we found out that if 2 brackets touched then we multiplied, but how do we do this? Well, -2 is just like saying "remove 2" and if we're multiplying we say "remove 2 GROUPS of". Now that just leaves the +3. "Remove 2 groups of +3) Well how can we remove anything if we don't have anything? Mr. Backe helped us with this and told us that we can take as many zeros as we can (zero pairs) and THEN take away whatever you need to take away.
We had homework on this and we were supposed to make up our own questions just like this one and solve it for quadrant 1 and 2. People shared their questions and we all solved them. Then we noticed that when you multiply a positive and a positive, then your product is also positive. We figured this rule would also go with the rest of the quadrants but with different products so we tried it out. We came up with a sentence for each quadrant.
We had a very long discussion about this and somehow it kept going 'till the end of class...which I was very happy about...no work....:)
Time for me to pick a scribe and get back to my Xbox360! ..hmmm.....
...*ahem*....yea, Bobby it's your turn >.> ................*ehem* PURPLE *cough*.... <<<<<< pretend that's purple 'cause I can't change my font color. The font color menu thingy won't open up -___-" oh well....
Wow! That's really cool how you use the quadrants. I never learned that way, but it makes a lot of sense. Good work for figuring out the statements for each quadrant, too.
Your diagrams are also pretty cool. I loved the flow chart-type one you made for (-2)(+3). Very cool! Keep up the good work!
