WebDec 5, 2013 · Because it clearly works. 4 - 1 = 3 (0100 - 0001 = 0011). The only way, to decrease an unsigned number with only an adder, is to overflow it. The fact, that we can't represent all positive numbers is the solution (with 4 bit is the unsigned maximum 15). For example we calculate 15 - 15 with 4 bit unsigned numbers. 15 - 15 is 0.
