The Joy of x

A concise journey through the basic principles of mathematics.
I enjoyed this book. Strogatz can vividly explain abstract mathematical principles.
In the past, I had to solve integrals at a reasonable level without really knowing what I was doing.
A math teacher lik Strogatz would have made all the difference. Strogatz shows the principles behind Algebra and Calculus in a very understandable way without explaining how to do it.

I read it with pleasure.
