Consider now $2,3 \in \ZZ$. We know that $2\cdot 3=3\cdot 2=6$ and this holds for every pair of integers.   We claim the same for bits, since for example  $$ 0\cdot 1\,=\,1\cdot 0\,=\,1\,.$$ 0\,=\,0\,.$$  We leave, as an exercise to the reader, to verify this for each $a,b \in \Fb$.\\  Again, this property can be formalized by saying that both the product in $\ZZ$ and the product in $\Fb$ are \emph{commutative}. In formulas, we say that for any $ a,b$ (which are elements of $\ZZ$ or of $\Fb$), we have  $$a\cdot b=b\cdot a.$$
