Re: Middle School Mathematics

Hi ganesh;


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.

Hi iamfriendly;

Just take and put your answers between the hide commands. I have done one of yours so you can see. Now just edit your post and you will see what I have done.
