Books like Asimov on Numbers

Though I'll admit that maths is not my strong point, and - beyond a few algebraic factorisations now and then - not my favourite pastime or topic either, I actually found this book thoroughly enjoyable. Asimov writes with a wonderful enthusiasm that is hard to not get drawn into, and combines this with a great sense of humour and the ability to explain clearly. I probably understand more about maths now than I ever did during highschool classes. Not for everyone, and I don't know how dated these concepts are, but I really liked this.
