V, Each step of an algorithm is always mathennatically precise. vi. The method call c-a. .sub (b) does the same thing as a-b. vii. Abstraction manages complexity by hiding implementation details. viii. Inheritance is a way to reuse the same code for different types of data. ix. In a sequence diagram, when one object's method calls the method of another, an arrow is drawn between the lines of both objects. x. To combine separate shapes into a drawable object whose parts move together, the Layer class is used. T 30) A quaternion is a kind of number which describes how physical objects pin. It combines 4 real number values, real, i.val, j val and k.val. ese values are a, b, c, and d, respectively, the quaternion is written .val, j- + bi + cj + dk. Write the functions init(self, r, i tr-(self) for the Python Quaternion class. val) and-st
