11. These operations represent the range of values for three integers that can represent 2^3 discreet, distinct values. This would allow representation of a any data set requiring 8 or less values, such as the octal # system. In the case of the octal # system we would be able to count and due simple arithmetic operations as long as our outcomes never exceeded 8 in value.
    We could represent 8 different students in a class, an alphabet with 8 letters, etc.
