• It is denoted by Z universally.
• Examples include: - 4, - 9, 100, etc.
• Remember that integers are rational numbers.
• There are two broad categories of number systems: real number (rational & irrational numbers, integers, whole numbers, natural numbers) & unreal numbers (complex numbers, imaginary numbers).
• Complex numbers are those which have a real and an unreal part. Example: $9 + 4i$ where $i = \sqrt{-1}$. These are in form of $\pm a \pm bi$ (i - iota).
• Imaginary numbers are those which are in form of $bi$ where b is a real number and $i = \sqrt{-1}$.
