Let 1 = x Multiply by x to get x = x^2 Subtract 1 from each side to get x - 1 = x^2 - 1 Divide both sides by x − 1 (this is a hidden division by zero as x = 1) (x - 1) / (x - 1) = (x^2 - 1) / (x - 1) 1 = ((x - 1) * (x + 1)) / (x-1) which simplifies to 1 = x + 1 Since x = 1, by substitution: 1 = 1 + 1, and therefore: 1 = 2 This is impossible. Hope this helps some with understanding why any number divided by zero is undefined.
