ive gotta rember thease rulez!

1. What was today’s topic?
2. Explain in your own words how to do the topic?
3. What does the vocabulary really mean?
4. How might you use the topic in a real life situation?
5. Can you find any interesting links about the topic?
6. Can you relate the topic to something else we have studied this year?

EQUASIONS AND INTERGERS! YAY!


Happy Thanksgiving!

Ok i REALLY dont want to do my blog but.... i have to so... im gonna get started!:'(
ok............. be positive %-) -ok there we go...
Today we r doin EQUASIONS AND INTERGERS! YAY!
Addition:

Rules:
Addition:
in addition when there is olny one negetave number you subtract and when there is two negataves you add.

GOT IT?

no i didnt eather so:

Ok so lets say you have a problem like this: 4+-7=?

1. You subtract 7-4 and get 3
2. Then you add the sign of the BIGGER number  
3.your answer is -3

Subtraction:
First something you have to know:
THERES NO SUCH THING AS SUBRACTION!!!!!!!!!! OMG!!!!!!!

I'll explain:

ok you've got this: -4-(-7) {hint ( ) thease dont mean anything}

you  HAVE TO make two marks

you turn the subtraction sign into an addition sign and make the negatave into a positive number-4+7
so now youve got an additon problem so you follow the addition rules

Now were gonna do division and multiplication!

With multiplication you have to follow thease rules:

With two negetaves you make the answer positive
With one you make the answer negatave

Lets do one!

1. you have a problem like this: 7x-2=?
2. 7x2=14 so the answer is -14

Ok now division

youve got a problem like this: -7/14=?
the rules are the same ad multiplication so the answer is -2

an intresting link is: http://classroom.jc-schools.net/basic/math-integ.html

you could use this in real life if you were in debt.

YAY! IM DONE!

C YA L8TR!!!!!!!

%-) -oh yea

solvin' algebratic expressions-IS FUN!

Happy Halloween!


Hello fello bloggerites!










Im gonna teach you how to do algebratic expressions! YAY! ok i got some food so now im PUMPED! Ok im gettin off topic.










Some things you have to know:





1.)The letter in the equasion {x+7=11} is called the varyable





how to do it with addition :










1.) you start with an EASY problem like this: 7+x=11





2.)you find the smallest number: 7 then you put it under both whole numbers with a - in this case: 7+x=11





-7 -7





3.) you see 7-7 cancels out so you have to do 11-7=4





4.) now you've got your answer! x=4










How to do it with subtraction:





1.) you start with ANOTHER EASY easy problem: 6-x=10





2.) you find the smallest whole number AGAIN: 6 than you put the numbers under the numbers with a - in this case: 6-x=10





-6 -6





3.) 6-6 cancels out so you bhave to do 10-6=4





4.) now youve got youre answer x=4










You think thats easy? well it gets harder- but not MUCH harder! [evil laugh] hahahahahahahahahah


Now we're gonna do it with DIVISON and MULTIPLICATION


first multiplication:


1.) first you've got a problem like this 7xp=14

2.) next you find the smallest whole number wich is 7 so you put it under each number 7xp=14

/7 /7

3.) since 7/7 cancels out you have to do 7/14=2

4.) Your Answer! p=2


Now... last but not least... DIVISION!!!!!!


1.) you have a problem like this: 2/p=4

2.)next you find the smallest whole number wich is 2 than you put it on each side with a / sign 2/ 2/p=4 /2

3.) 2x2 cancels out so you have to do 2/4=2

4.) the answer is p=2


WERE DONE RIGHT!- WRONG


A way we could use this in real life is as a banker .




wooh now im DONE -yay.


goodbye- peace out! %-) oh yea

scientific notation /exponents

Hello there im posting my first REAL blog thing.......... ok im gonna get started now. First of all i'm gonna start with scientific notation. Scentific notatation is basicly a easy way to write BIG numbers,you do it by taking 1,240,000,000,000 for example,take the first numbers that arent zero {124} and drop the zeros and put a decimal before the first number {1.24} thats your first number [1.24 x _ ]. Next you count the zeros there is 11 in this case.So the exponent is 10 to the 11'th power. [1.24 x 10 to the 11 power] you could find practice stuff about scientific notation at.........http://janus.astro.umd.edu/astro/scinote/

you can use this in real life by caculateing the distance to the sun or fnding the dencinity of plannets. its mainly used in astronomy.http://en.wikibooks.org/wiki/Astronomy/Scientific_Notation

that was my first blog and there will be MANY to come

re:this is my first blog

ROTGLMFHO yea this is another test blog LOL :-)
