But if the definition of a group uses the stronger axioms(2 sidedness and uniqueness are assumed), then it'll work fine. A(A +B)−1B(A−1 + B−1) = A(A +B)−1(BA−1 +I) = A(A +B)−1(A + B)A−1 = I A ( A + B) − 1 B ( A − 1 + B − 1) = A ( A + B) − 1 ( B A − 1 + I) = A ( A + B) − 1 ( A + B) A − 1 = I. $$\text{if}(a \ge b, a, b) = \text{if}(a \ge b, \frac 1 2 (a + b + a - b), \frac 1 2 (a + b + b - a))$$ $$\text{if}(a \ge b, a, b) = \text{if}(a \ge b, a, b)$$ Share. I figured I could use this, because in the event that a and b have magnitude less than 1, that you can re-arrange the equation to get the same starting form.S.
