### Scribe Post For Nov 10. 2008

Today in class the first thing we did was look over our homework which was done in the blue barn yard.

Then he gave us homework from page 5 in the green booklet. He made us pick 4 questions and each and to be from the coordinate chart and we had to illustrate them. The other eight we just had to write the answer. Here are the 4 I picked.

1) (3)(9)=

Which is from the quadrant 1 and it means 3x9. Here's how I answered it...

This represents 3 groups of 9 which equals to 27.

2) (-12)(3)

This question is from quadrant 2. Here's how I answered it....

This represents 3 group of- 12 getting removed. The answer equals to - 36.

3) (6) (-2)

This question is from quadrant 3. Here's how I answered it...

This shows 6 groups of -2 which equals to -12.

4)(-5)(-4)

This question is from quadrant 4. Here's how I answered it.

This shows -5 groups of -4 getting removed, which equals to +20.

(-)(-)=positive

(-)(-)(-)=negative

(-)(-)(-)(-)=positive

(-)(-)(-)(-)(-)=negative

(+)(-)= negative

(+)(-)(-)=positive

(+)(-)(-)(-)=negative

(+)(-)(-)(-)(-)=positive

The rule when multiplying a negative integer with a negative integer the product is always a positive. When multiplying a positive integer with a negative integer the product always equals to a negative.

The patterns I noticed were that the answers were positive then negative and vice versa. Each time you went down they would add a second integer.

For the next scribe I pick Angela. Thanks and please leave a comment. :)

He also gave us homework to find the pattern, what we noticed, to make a rule and anything else for this...

This is how I answered it.
