And in general, keep in mind that what you have in school is just the basics. When you are forced to prove various theorems, learn to extract the square root of negative one, divide zero by zero, and infinity by infinity, then you will gladly want that basic school mathematics... I already miss it: smile05:
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
