From imaginary numbers to the fourth dimension and beyond mathematics has always been about
imagining things that seem impossible at first glance. In x+y Eugenia Cheng draws on the
insights of higher-dimensional mathematics to reveal a transformative new way of talking about
the patriarchy mansplaining and sexism: a way that empowers all of us to make the world a
better place. Using precise mathematical reasoning to uncover everything from the sexist
assumptions that make society a harder place for women to live to the limitations of science
and statistics in helping us understand the link between gender and society Cheng's analysis
replaces confusion with clarity brings original thinking to well worn arguments - and provides
a radical illuminating and liberating new way of thinking about the world and women's place in
it.
