Ones' complement

Ones' complement is a way of representing numbers and it's used in computer programming and math. Basically, it's a way to represent a number as a combination of ones and zeros (also known as binary). Ones' complement is a set of rules that tell us how many ones and zeros we need to represent a specific number. For example, if we wanted to represent the number 5 in ones' complement, we would write it as 0101, which means one zero followed by four ones. This is because, according to the rules of ones' complement, the number 5 is represented by four ones (in binary, four ones is equal to five).
