************************************** Recall this from grade school: a * b = a + a + ... + a {b times} ************************************** Substitute x for a and b: x * x = x + x + ... + x {x times} ************************************** Differentiate both sides: 2 * x = 1 + 1 + ... + 1 {x times} ************************************** Simplify 1 + 1 + ... + 1: 2 * x = x ************************************** Assume x isn't 0, cancel it from both sides: 2 = 1 **************************************
