Pluses and Minuses: How Math Solves Our ProblemsA guide to changing how you think about numbers and mathematics, from the prodigy changing the way the world thinks about math. We all know math is important: we live in the age of big data, our lives are increasingly governed by algorithms, and we're constantly faced with a barrage of statistics about everything from politics to our health. But what might be less obvious is how math factors into your daily life, and what memorizing all of those
A guide to changing how you think about numbers and mathematics, from the prodigy changing the way the world thinks about math. We all know math is important: we live in the age of big data, our lives are increasingly governed by algorithms, and we're constantly faced with a barrage of statistics about everything from politics to our health. But what might be less obvious is how math factors into your daily life, and what memorizing all of those formulae in school had to do with it. Math prodigy Stefan Buijsman is beginning to change that through his pioneering research into the way we learn math. Plusses and Minuses is based in the countless ways that math is engrained in our daily lives, and shows readers how math can actually be used to make problems easier to solve. Taking readers on a journey around the world to visit societies that have developed without the use of math, and back into history to learn how and why various disciples of mathematics were invented, Buijsman shows the vital importance of math, and how a better understanding of mathematics will give us a better understanding of the world as a whole. Stefan Buijsman has become one of the most sought-after experts in math education after he completed his PhD at age 20. In Plusses and Minuses, he puts his research into practice to help anyone gain a better grasp of mathematics than they have ever had.Binding Type: Paperback

For a very petite wrist
I have a child-size wrist at 5.5 inches. It is hard to find watches small enough! This watch has a 6 inch fit, fitting my arm with a little wiggle room.
It has spring sides for ease of putting it on, but won't allow for stretch or adjustment. Therefore, it will be tight on a standard 7 inch wrist.
I am delighted with my purchase, but was hesitant to buy based on unclear size. I wanted to clarify for you the actual size to expect.
I included a pic from the top and bottom of watch on my wrist, hoping to demonstrate the snug size on a tiny arm.
It's a beautiful watch with unique style, and fit.
