This means that they are separate and distinct entities. In fact each of these sets is countable. The last set, R , cannot be counted. This is because they are continuous. Between any two real numbers, however close they may be, there are infinitely more real numbers. At higher levels of secondary and tertiary education discrete mathematics , is often more challenging than the mathematics of continuous functions. With continuous functions, a small change in the input variable leads to a small change in the output variable.

Smooth, continuous functions lead on to most of the functions students meet at secondary school, including calculus at the senior secondary school level. The numbers we meet at school are generally represented by using combinations of ten number symbols also called numerals or digits plus the symbols ".
