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)) / (x1) 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.
