Detailed explanation-1: -The result of inverting the bits in a number is called the one’s complement of that number. For example, the one’s complement of 0110111 is 1001000. It is called the one’s complement because when you add the numbers together, you get all 1’s. For example, 0110111 + 1001000 = 1111111.
Detailed explanation-2: -For example, 1’s complement of binary number 110010 is 001101. To get 2’s complement of binary number is 1’s complement of given number plus 1 to the least significant bit (LSB). For example 2’s complement of binary number 10010 is (01101) + 1 = 01110.
Detailed explanation-3: -8’s complement of octal number is 7’s complement of given number plus 1 to the least significant bit (LSB). For example 8’s complement of octal number 320 is (777-320) + 1 = 457 + 1 = 460.
Detailed explanation-4: -Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees. One way to avoid mixing up these definitions is to note that s comes after c in the alphabet, and 180 is greater than 90.
