Mathematics is a world of shapes, symmetries, and logical ideas. And in that world, the boundary between things being equal and unequal is a gray area, or perhaps a rainbow of beautiful, vibrant, subtly nuanced color.  \u003cbr\u003e   \u003cbr\u003e As \u003ci\u003eUnequal \u003c\/i\u003eshows, once you go over that rainbow, almost everything can be considered equal and unequal at the same time, whether it’s shapes (seen from the right perspective, a circle is the same as an ellipse), words (synonyms), or people—even numbers! That’s because mathematics isn’t a series of rules, facts, or answers. It’s an invitation to a more powerful way of thinking.    ","brand":"Basic Books","offers":[{"title":"Default Title","offer_id":45204392247474,"sku":"9781541606555","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0536\/7418\/0786\/files\/O_6e1ef91a-4ef4-424d-83cd-24ee0c107987.jpg?v=1772439825","url":"https:\/\/shop.hachettebookgroup.com\/products\/unequal-2","provider":"Hachette Book Group","version":"1.0","type":"link"}
