### Scribe Post for November 3, 2009

Wednesday, November 4, 2009
Hey 9-05! I'm really sorry for the late post! Okay, a recap about tuesdays math class. We started off class with 20 minutes of work time. We worked on pages in the textbook. Also, we talked about dividing negative and positive numbers. Just before I explain about dividing negative and positive numbers I would like to tell you guys about what we learned about equations mean in sentences.

x+y=z

x-y=z
minuend subtract subtrahend equals difference
x÷y=z
dividend divided by divisor equals quotient

(x)(y)=z
factor multiplied by factor equals product

You guys should try to memorize this because we might need it. Anyways, back to dividing negative and positive numbers.
If the dividend and divisor are both positive the quotient will be positive.
If the dividend and divisor are both negative the quptient will still remain positive.
If the dividend is positive and the divisor is negative the quotient will be negative.
If the dividend is negative and the divisor is positive the quotient will be negative.
-----------------------------------------------------------------------------------------
We also talked about Order of Operations. Mr.B told about casey's question. It was something like this.

What did he do wrong there? He thought since they're was three decimal places the answer will have three decimal places. Casey should've thought about the order of operation. (BEDMAS)

Parenthesis (Brackets)
Exponents
Division
Multiplication
Subtraction

I am really really sorry! I was having a hard time on the division. Please comment and help me out please! This gave me a headache. Also, I'm sorry there isn't alot on this post, but please comment and help me learn from my mistakes so next time I'm the scribe I will do a better job! 9-05 all the way ! :) Oh, and the next scribe is ADRIAN R ! :)

See not so bad. Label, division of integers. Check quotient... what is the right way to do Casey's question?

Great Job! Just one thing, for the homework you forgot to say about the pages apply, and extend. To do all those questions :(. Otherwise great job!

Great job Tracey! You spelled quotient wrong. In the pictures, you should use different colours for the positive numbers and negative numbers. So you would at least have more colour in your post. For the division you should have used some examples but you said you were having a hard time with it, you could have added a video instead of examples if you didn't understand that well. But you did a good job explaining the division, great job again.

Great job on the post Tracey! I agree with Zerlina, go check you're grammar, spelling, and solutions every time you hit publish. But overall, you did great! :D
