The 1's complement is formed by inverting every binary digit (bit) of the number - if it is a 0 it becomes a 1, otherwise it is a 1 and becomes a 0.
If 10 is in base 2, then its 1's compliment is 01 or just 1.
If 10 is in base 10, then in binary it is 1010 and its 1's complement is 0101 = 5 in decimal.
However, if more bits are being used to store it, there would be leading 0s that get inverted to 1s and so the resultant number is different; examples:
8 bits (a byte): decimal 10 = 0000 1010 → 1111 0101 = 245 in decimal
16 bits: decimal 10 = 0000 0000 0000 1010 → 1111 1111 1111 0101 = 65525
Next, if 2s complement is being used to represent negative numbers, the binary 1111 0101 represents decimal -11; similarly 1111 1111 1111 0101 represents decimal -11.
To get the 2s complement, find the 1s complement (by inverting the bits) and add 1. Assuming that number is [4-bit] binary it would be 1000. If it is preceded by 0s, as in, for example, 0000 1000, then it would be 1111 1000.

The complement involves probability. Say the probability of choosing a red marble was 3/10. So the complement, or the chance of not choosing a red marble is 7/10. Think of it as the opposite of the probabilty. You simply subtract the numerator from the denominator and you have the complement. (10-3=7 in this case, then you would put your difference over the probabilities denominator, so it would be 7/10.)
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
The decimal complement of the number 1 is 8. You can find the complement of any digit by subtracting it from the largest single digit value in the base that you're working in.
8-bit 2s complement representation of -19 is 11101101 For 1s complement invert all the bits. For 2s complement add 1 to the 1s complement: With 8-bits: 19 � 0001 0011 1s � 1110 1100 2s � 1110 1100 + 1 = 1110 1101
Invert the bits of each number in the binary sequence (change all 1s to 0s, and all 0s to 1s). So, you would have: 100110101 (original number) 011001010 (one's complement)

9's complement of a decimal number represented in 2421 code is easily obtained by replacing the 1s with 0s,and 0s with 1s,so 2421 code is called a self complementing code.example-2421 of '2' is '0010',after replacing the 0s with 1s and 1s with 0s weget '1101' which is the 2421 of '7'(9s complement of 2 is 7). Thus 2421 code is self complementary.
what is the verb complement
The complement of a number is what needs to be added to make a specific value. Typically when dealing with complements of a number a base of 10 is used (complement of 9 is 1 since 9 +1 = 10). In the case of four tenths, the complement would be 6 tenths 4/10 + 6/10 = 10/10 or 1
To get the 2s complement, find the 1s complement (by inverting the bits) and add 1. Assuming that number is [4-bit] binary it would be 1000. If it is preceded by 0s, as in, for example, 0000 1000, then it would be 1111 1000.
