Square Root System
This is my square root system from math.com.
Many mathematical operations have an inverse, or opposite, operation. Subtraction is the opposite of addition, division is the inverse of multiplication, and so on. Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 …
The square root of a number written
is the number that gives n when multiplied by itself.
Finding square roots of of numbers that aren't perfect squares without a calculator
1. Estimate - first, get as close as you can by finding two perfect square roots your number is between.
2. Divide - divide your number by one of those square roots.
3. Average - take the average of the result of step 2 and the root.
4. Use the result of step 3 to repeat steps 2 and 3 until you have a number that is accurate enough for you.
Example: Calculate the square root of 10 () to 2 decimal places.
1. Find the two perfect square numbers it lies between.
Solution:
32 = 9 and 42 = 16, so lies between 3 and 4.
2. Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
3. Average 3.33 and 3. (3.33 + 3)/2 = 3.1667
Try the answer --> Is 3.1623 squared equal to 10? 3.1623 x 3.1623 = 10.0001
If this is accurate enough for you, you can stop! Otherwise, you can repeat steps 2 and 3.
Note: There are a number of ways to calculate square roots without a calculator.

Multiplication System
This is my multiplication system from math.com.
You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.
Positive x positive = positive
Negative x negative = positive
When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.
Positive x negative = negative
Negative x positive = negative
When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.
Positive ÷ positive = positive
Negative ÷ negative = positive
When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.
Positive ÷ negative = negative
Negative ÷ positive = negative

Charlie Green's Post
You know what? Those posts you were just looking at, the first two posts, those are coming from other internet pages. Like the weather, that was from iGoogle, and that math system thing, that was from math.com. Pretty weird, huh?
Tonight, I am going to Porter's birthday party, which is gonna be really fun. Porter looks like this.

Porter is a great friend of mine, but not like Lexi. She's my best friend. She's been my best friend for like six years. Here's a pic of her with Ashlyn, Matilda's best friend.
I already know you've seen this pic, but just take one more look at it. JUST LIKE THAT!!! Mom just told me about how online games can be so addicting. I already knew that, because of Uncle Jason Green.

Hi, it's Charlie. I made a new animation called Lego War. I have it on my VideoImpression program. But I can't put it on the internet, because Blogger only says you can import (or export, I think) Windows Media Player vids, RealPlayer vids, and QuickTime vids. That's just rude.
I hate the new version of Blogger, because of the storing vids. It won't store vids into posts, because it doesn't say you can. I tried to store a recording of Lego War, but it failed all three times. I miss the classic version.
Well, I am gonna try to add pretend team members to my blog, so bye.

My Experience from Today
I had some fun today. I was at the IDC cleaning up, because we wanted to be helpful to the teachers. I cleaned up the play place the whole time, really. Old teachers I used to know were there today, so it was kind of meeting the people.
I also went to Laurie's for Melanie's birthday lunch party. I didn't have a fun time at all there. AT ALL!!! But I wrote a new story called Criminal Horse. It's about a horse that killed its owner, and the horse's name was Murray, because he made the sound, "Murreee!!!" So, yeah!!!
Bye, bye!!!
