The numbers we are interested in are integers, which we collect in a set called   $\ZZ=\{ \ldots,-1,0,1,2, \ldots\}$, and rational numbers, which we collect in a set called $\QQ=\{ \ldots,\frac{-5}{101}, \frac{1}{2},0,3,\ldots\}$.   \\  In the following table, Since $\Fb$ is so small,  we can see use just the following table to show  how to sum and multiply bits. \begin{table}[!htb]  \centering

\caption{Sum and product}\label{SumProd}  \end{table}    The first column and the secondone  contain the values of two input variables, $a$ and $b$, used here to represent representing  the two bits wehave to  sum or multiply; the third and the fourth ones, fourth,  respectively, contain theresults of the  sum and the product of $a$ and $b$.\\ \medskip   %Performing operations with bits is not the same as doing so with %``usual''
