Why negative times negative is equal to positive?
Using the distributive property of multiplication over addition, x*[x - x] = x*[x + (-x)] = x*x + x*(-x)LHS = x*0 = 0RHS = x^2 + x*(-x)Therefore x*(-x) = -x^2 and, by commutativity, -x*x = -x^2Next-x*[x - x] = -x*[x + (-x)] = -x*x + -x*(-x)LHS = -x*0 = 0RHS = -x^2 + -x*(-x)Therefore (RHS) -x times -x = +x^2 (LHS).
