The numbers we work with in Mathematics can be represented using set notation. In CSEC General Mathematics, we were limited to the set of real numbers ($\mathbb{R}$) which is the set of all positive and negative whole and decimal numbers and zero ($0$). Simply put, the real numbers are every number you have come across so far:

Positive whole numbers e.g. $2$ and $5$
Negative whole numbers e.g. $-13$ and $-27$
Positive decimal numbers e.g. $2.4$ and $0.5$
Negative decimal numbers e.g. $-1.6$ and $-40.002$
Zero ($0$)

The set of real numbers has subsets (a set within a set) that have special properties.
