It's a new-fresh way of thinking. Socially liberal, socially pissed-off, and fiscally conservative. F*ck off, but I love you, and I want government out of our lives as much as possible.

The nontrivial solution to the equation a + b + c = a × b × c, where a, b, and c are positive integers—the sum and the product of three whole numbers are the same.
Besides 1 + 2 + 3 = 1 × 2 × 3, the numbers 1, 2, and 3 form the set of three integers such that each divides the sum of the other two, and their reciprocals show that the number 1 can be expressed as the sum of three unit fractions: 1 = 1/2 + 1/3 + 1/6.
