"Complex" numbers have two parts, a "real" part (being any "real" number that you're used to dealing with) and an imaginary" part (being any number with an "i" in it).
The "standard" format for complex numbers is "a + bi"; that is, real-part first and i-part last.
Do not confuse the complex numbers with the pure imaginary numbers. Every real number is a complex number and every pure imaginary number is a complex number also.
