Multiplying Algebraic Fractions
Remember when you learned how to find the prime factorization of a number in Grade 6? Here's a review with a bit of algebra included. You need to understand this before the quiz next Monday.
Remember... the quiz is on Monday, October 16.

Hey Mrs. Burke!
Though Manassas didn't go as well as I thought it would, hopefully Gettysburg won't be the same.
I went on the site and it looks pretty cool! I tried to go to Social Studies to watch a movie on the Civil War, but I have to register first.
I'm a little worried about the quiz but I'm sure I'll be prepared by Monday!
See you tomorrow,
AMS
Hi Mrs. Burke!
I'm home from Gettysburg. I had a lot of fun!!!!!!
The tour guy from the last tour asked us a question with some mathematical terms.
What was the question? I want to figure it out!
See you on Monday!

I checked out the link and reviewed the factor tree model and I learned the cake model for prime factorization. I also learned that monomials are combinations of real numbers and variables such as x and y. I took the pop quiz and scored 10 out of 10. Will monomials and the cake model be on the quiz? :)
Hi I looked at the website and took the pop quiz. On one question it said that a prime number is any number greater than zero with exactly two factors. Why is it that negative numbers cannot be prime? And wouldn't -3 * -1 equal 3, as well as 3 * 1, so that 3 would have four factors?
Hi Mrs. Burke,
I agree with Patrick. If the defenition of a prime number is that any number greater than one (not zero) with exactly 2 factors, then prime numbers do not exist. They would be imaginary numbers, I suppose.
I think prime numbers can be negative because if a positive and a negative number are multiplied, their product is negative. Therefore, every positive prime number's (if they exist) opposite must also be a prime number. For example, 7 is a prime number because it only has two factors, 1 and itself. Therefore, the only factors of -7 are 1 and -7. Oh! But then there's also -1 and 7. So, there can be no negative prime numbers. I'll reexplain.
A prime number can not be negative because a prime number is a number with the only factors of 1 and itself. Since any negative number has atleast 4 factors, they can not be prime. For example, the factors of -7 = 1 and -7, -1 and 7. This goes for any negative number as long as (in this case) the 7 is replaced by the opposite of the "examined" number.
This makes so much sense! However, I hope my explanation won't confuse anyone.
See you on Monday!

P.S.: I think this is my best post yet!!!
