Example [■8(3&[email protected]&4)][■8(3&[email protected]&[email protected]&3)] We cannot add them But we can add [■8(3&[email protected]&4)][■8(−9&[email protected]−1&3)] We can add them [■8(3&[email protected]&[email protected]&3)][■8(−2&[email protected]−8&[email protected]&−18)] We can add them [■8(3&[email protected]&4)]+ [■8(−9&[email protected]−1&3)] =[■8(3+(−9)&[email protected]+(−1)&4+3)] =[■8(−6&[email protected]&7)] [■8(3&[email protected]&[email protected]&3)]−[■8(−2&[email protected]−8&[email protected]&−18)] =[■8(3−(−2)&2−[email protected]−(−8)&4−[email protected]−0&3−(−18))] =[■8(3+2&−[email protected]+8&−[email protected]&3 +18)] =[■8(5&−[email protected]&−[email protected]&21)]
