Math Help... Answers needed!?

Question:I was wondering if anyone can explain how to add, subtract, divide, or multiply polynomials. I need step by step instructions, and they need to be basic to read and understand. It's for eighth grade math=) If you can help me with all of the above, thts great, but if u can only help me in one area (i.e adding polynomials) thts appreciated too. If you can give me websites tht show the basic steps, that would be great too.
thanks!

One, learn to spell; this is very helpful.

Two, utilize an Algebra book.

There ya go, lots of answers for you.
4x+(5x+7)= 9x+7
add the coefficients of same degree
4x+(5x^2+7)=5x^2+4x+7
don't add coefficients of different degrees
(5x^2+4x)(2x+4)=10x^3+28x^2+16...
FOIL
I know how to do them, but the websites might be a bit better at explaining on the computer:

Adding:

Subtracting: http://www.purplemath.com/modules/polyad...

Multiplying:

There are about three pages on the internet per explanation, so be sure to click the next button at the bottom of each page.

Hope this helps!
My favorite site for math questions is: http://mathworld.wolfram.com/

As for operations on polynomials, that would take quite some time to cover all the important details. In fact, I would think that is what 8th grade math is for.
well i would say just use your book but back when i took algebra my book confused me more than helping me...

Ok to add polynomials you put the nomials in order of degree... such as 2xto the 3rd x to the 2 and x... then you just combine your like terms... if you have 4 x to the 3rd and 6 x to the 3rd then it 10 x to the 3rd and you just move down the line- subtraction is the same only you subtract like terms instead of adding them- now multiplying and dividing is stuff I DO NOT remember how to explain... lol
Check out this link. There is a search bar in the top right corner...enter what you are searching for. Example: add polynomials. Pick from the search results. This web site is a great math resource. They give easy to understand step by step instructions for just about anything math related. I have used this site for high school and college.good luck and hope it helps.
