1. Let $$ s $$ be a sel. Prove that the law of multiplication defined by $$ a b=a \quad \forall a, b \in S $$ is associative. (3 mks)

Question

Martin Schmidt · Accepted Answer

To prove the multiplication $$ ab = a $$ is associative, we show that $$ (ab)c = a $$ and $$ a(bc) = a $$ for any $$ a, b, c \in S $$. Both sides simplify to $$ a $$, proving associativity.
