We claim that this holds \emph{also} for the sum of bits. For example
$$ (1+0)+1=1+1=0=1+(0+1)=1+0+1 \,.$$
The reader can verify our claim for any $a,b,c \in \Fb$.\\
In Algebra, any Any time we have a set and a sum operation which satisfies the general property
$$ \forall a,b,c, \quad (a+b)+c\,=\,a+(b+c)\,=\,a+b+c \,,$$
we say that the operation is \emph{associative}.\\
Therefore, we can conclude that both the sum in $\ZZ$ and the sum in $\Fb$ are associative operations.
