So I'm at a college camp, enjoying free time and dormitory experience. I just finished this book.
It was enjoyable. It turns out many of math's roots stem from finger counting and the abacus. That was a truly ingenious invention. They should return them to grade school education as they provide visualization of all basic math.
In addition I was impressed with the later, advanced chapters. As being on the verge of taking BC calculus next year, I'm excited to see new ideas and concepts, particularly the ideas around infinity. I don't completely understand it but it is a logical first taste. And I'm still impressed with the information that "calculus" means pebbles in Latin.
