I got different answers than you on #3 and #4.

On #3 I got -7x^2 for the x term.

On #4 I got -1200x and -800 for the last two terms.

Our answers agreed on the rest.

Have a great day!

*ignores what has just been said and does the actual exercise*

I will the rest later.

You are right. There is always resistance (inertia in action) to change and to different ways of doing things. There have been lots of movements throughout history that were resisted mightily but in the end came about, especially in religion and government. I enjoy pointing out easier ways of doing mathematics as well as problems in the language. Whether someone likes it or not is up to them. It is against my nature to "put someone down" over much of anything much less mathematics.

But I can't vouch for others. If there should arise some "bad blood" it may be over something I said but I'm not likely to be a participant in the "bad blood." I have pretty much of a "live and

let live" philosophy. Math should be interesting and fun to participate in, not something to get

all upset about. My heart is to help folks to understand and enjoy math more. Disagreement is

part of the nature of mathematics. I doubt that any two mathematicians would agree on every-

thing they know in common.

All that being said I may dare to ask some questions or make some observations occasionally that

others may think are a bit different or strange. Hopefully such will stimulate some thought about

how we say or do math. The idea is to make math more "user friendly."

I can see your signature but you have not been a member long enough for it to appear. You signed up 7 / 20 / 2012 which is not quite the grace period yet. Have patience it will appear.

Where would a thread concerning "the language of mathematics" fit in? Would we have to

create a new thread to deal with this?

I am glad you asked that question before you went and did it.

Discussions like that can easily get out of hand. I have already had step in on another thread to stop the bickering.

People who feel that mathematics is a little funky always get the sternest resistance. People will come in from other forums to attack them. Pretty soon there is bad blood and I am forced to act like Mussolini.

I have been on both sides in those arguments and have seen the mayhem they cause on other forums.

That is just my experience and I am certainly not going to censure anyone based on what might happen. Start your thread in Members only or Dark discussions and good luck.

]]>In fact these divisions can be done by the "usual method" (repeated subtraction algorithm) much faster if one just writes the coefficients of the powers of x. After all polynomials are a place value system just like base 10 arithmetic. The main difference is that it is place value in an unknown base x. As such one cannot carry or borrow. This makes the arithmetic of polynomials easier than base 10 arithmetic. And it is not just division that can be done easier in this short form.

Adding, subtracting, multiplying and factoring can be done easier also.

Hi bobbym!

My signature still doesn't show up, does it? Am I doing something wrong that it won't work?
