... A1: If a and b belong to S, then a + b is also in S A2: a + (b+c) = (a+b) + c for all a,b,c in S A3: There is an element 0 in R such that a + 0 = 0 + a = a for all a in S A4: For each a in S there is an element –a in S such that a + (-a) = (-a) + a = 0 A5: a + b = b + a for all a,b in A M1: If a and ...

... • BCD is wasteful of bits. • The conversion between BCD and binary is complicated. Thus most arithmetic operations are done with binary rather than other representations. (However it is possible to implement arithmetic in BCD but with a carry between the columns). ...
