A more general object is the "cancelation ring" in which non-zero members do NOT necessarily have multiplicative inverses but if ab= 0 and a is not 0, then b= 0. In that case, if ab= ac, ab- ac= a (b- c)= 0. Since a is not 0, we must have b- c= 0 and so b= c.

Chapter 10 Class 12 Vector Algebra. Serial order wise.
WebThe idea is that if a not equal to 0 then b = 0 also applies to the case when b is not equal to 0 then a = 0. The proof sometimes will clarify this but it might be left unstated. The idea is that ab = 0 is symmetrical for a and b, ie ab = ba so picking one essentially "proves" it for the other. 3 Reply [deleted] • 3 yr. ago WebSolution for 1.3.4 Indicate whether each statement is true or false.
