Explanation: In most cases the value of two’s complement is different from the original value. However, there are cases in which the two’s complement value may be equal to the original value. For example, the two’s complement of 10000000 is also equal to 10000000. Hence the statement is false.

2. The one’s complement of 110010101 is:

a) 001101010

b) 110010101
