What is Subtraction?

Subtraction, third in the Mathemafiction series, is here, there, and everywhere good books are sold, or at least it soon will be, because all booksellers will surely want to know what happens to a subtracted life. Subtraction is here anyway–just click on the link.

But what is Mathemafiction? I’m a mathematician, so mathematical ideas come naturally to me. But not, mathemafiction is not about learning to do math.

51xcie2u2blThe first novel, Divide by Zero, told the story of a strong community divided by tragedy. Why Divide by Zero? Because division by zero results in an undefined answer–it all depends on the initial conditions and the details of the equation. Divide x by x and you’ll always get 1. Divide 2x by x and you’ll get 2. Divide x squared by x and you’ll get x, which is 0 when x is 0. But divide 1 by x and you’ll get something that grows infinitely large as x grows small. When the subdivision of Paradise is divided by a violent crime… will it explode or unite around a finite solution?

512bbjmvzuflThe second Mathemafiction novel is Infinite Sum. It tells the story of a mother weighed down by the “infinite sum” of her troubles. She has a troubled past. She paints troubled pictures. And her perfect family and marriage might fall apart. The thing is, some infinite sums add up to nicely finite solutions. Try adding 1 plus 1/2 plus 1/4 plus 1/8 plus 1/16…. The more terms you add, the nearer you get to 2, which isn’t infinite at all. Will a mother’s sum of troubles sum to something manageably finite as well?

51ryws67wolThen there’s Subtraction: A man whose had everything subtracted from his life… a man alone, who’d rather keep it that way since relationships only end in someone being hurt… a man who trusts no one, teaches math, and despite everything cares deeply for his students… What happens when this last thing that matters is threatened, when an autistic child is subtracted from his class? But subtracting a negative number is the same as adding a positive, and this teacher’s negative attitude just might change over the course of the novel.
