Hi soroban;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

"Shoot C", indeed!


When you're old and your eyes are dim, There ain't no old shep gonna happen again
We'll still go walking down country lanes, I'll sing the same old song
Hear me call your name
