\medskip  The set containing $\Fb[x]$ contains  allthe  polynomials in the variable $x$, $x$  whose coefficients are bits is denoted by $\Fb [x]$:  $$\Fb [x] := \{1,x,x+1,x^2,x^2+x,....\}.$$ bits:  $$  \Fb [x]\, =\, \{1,x,x+1,x^2,x^2+x,....\}\,.  $$  The notation is the analogue of that for polynomials over $\RR$, whose set is   usually denoted by $\RR[x]$.\\  In analogy with $\RR[x]$, we can define the \emph{degree} of a monomial
