What is the two's (2's) complement. You learn the trick to calculate it for any number such as binary, positive and negative (e.g. of 1010, 43, 00000000, -17, 11111) using the one's (1's) complement. An example of a logic circuit design using a 4-bit full adder to show how the 2's complement is determined by a computer.
