The adder circuit according to the subject of the invention has a main circuit (1), which consists of 14 or 15 individual adder circuits (12), and in the output area only one one-upwards shift circuit (3). The circuit (1) must process the formation of the sum 9 + 4 + 1 as a maximum. This sum formation arises because in this case the AND circuit 42 also has high potential at its output. Thus not only is the circuit (1) at high potential at all its outputs, but the lines u, k and z are also at high potential, which concludes this sum formation. <IMAGE>
