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
