Proposed conventions include assigning the operations equal precedence and evaluating them from left to right, or equivalently treating division as multiplication by the reciprocal and then evaluating in any order; [10] evaluating all multiplications first followed by divisions from left to right; or eschewing such expressions and instead ...
The k th step of the algorithm gives the equation r k = r k−2 − q k r k−1. Since the recursion formula has been assumed to be correct for r k−2 and r k−1, they may be expressed in terms of the corresponding s and t variables r k = (s k−2 a + t k−2 b) − q k (s k−1 a + t k−1 b). Rearranging this equation yields the recursion ...
