2x = x2, is this correct?hello #2 20131021 03:36:50
Re: 2x = x2, is this correct?
You can say ( x + 1 ) = ( 1 + x ). It does work for 2. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20131021 04:10:29

The sign goes in front like this 2. That is negative 2. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
