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
