Demonstartion of a four bit adder
Set A to 0110 (decimal 6), Left DIP 6,7 ON
Set B to 0100 (decimal 4), Right DIP 6 ON
Note that Sum = 1010 (decimal 10)
Click on Cin, Carry In. This adds one, Sum = 1011 (decimal 11)
Set A to 1011 (decimal 11)
Set B to 0111 (decimal 7)
Note that Sum = 0010 but Carry out is on. The sum is therefore 10010 (18 decimal)
