Representing Integers in the Binary System
One solution is to use the leftmost column to indicate the sign of the number:

  • if it contains a 0, the number is positive

  • if it contains a 1, the number is negative

    NB: There are other ways to represent positive and negative numbers in computer science but we will omit them.
