Maths Quotes

There is something I don't understand about algebra: It has been around for thousands of years, yet no one has ever found out what the value of "x" or "y" really is.

Richard van der Merwe

In mathematics the art of proposing a question must be held of higher value than solving it.

Georg Cantor
