Scribe Post for November 13, 2008

Today in class checked our homework (green booklet pg. 5, 13-18) to make sure our answers are right. We spent most of the class on this. Since you already know the rules/theorem for multiplying integers, I will talk about the "new" thing we learned in class.

We learned what to do with questions like this:

Since there is **no sign** between the -2 and the *bracket*, that means you have to **multiply**. To solve this question, put the -2 in *brackets*:

Then solve the question like you would normally. Remember, there is an even number of negative integers in this question so the product will be positive.

The answer to this question is +6.

We also learned how to solve questions where the negative sign is **outside** the *bracket*. Like this:

That negative sign, all **by itself** means -1. So the question will now look like this:

(-1)(2)= -2 . Now we answer the rest of the question:

You can also do it this way:

When you see a

negative sign beside a

bracket (uh-oh) you

change the

integer to a

positive.

Well that's all for today. Remember, homework is the green booklet pg. 5, questions 19 - 36. I hope my pictures weren't **too **bad ;). I choose **Elmane **as the next scribe. Please leave comments. Thanks for reading!

Anyways, you did good. You always do. :)

Good Job!

Well done! Good pictures. Your explainations were great and really clear. It felt like I was talking to you rather than reading your typing. Keep up the awesome posting! :)
