Hi ganesh;

In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

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.
