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
addend plus addend equals sum

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
Addition
Subtraction
