Questions regarding proof of "if ab = 0 then a = 0 or b = 0"

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 Web22 mrt. 2024 · Ex 10.3, 14 - If either a=0 or b=0, then a.b = 0, but converse Chapter 10 Class 12 Vector Algebra Serial order wise Ex 10.3 Ex 10.3, 14 - Chapter 10 Class 12 … so was synonym
