(4go what they r called; they aint irrational) numbers.
so that clearly states:
"tell me what the heck they were called" 
So to sum up and to explain properly:
rational numbers:
numbers having a terminating decimal point.
in other words, numbers which can be written as a fraction.
eg: 9/4 = 2.25
irrational numbers:
numbers which don't have a terminating decimal point.
in other words, numbers which can not be written as a fraction.
eg: pi = 3.14159265359....
complex/imaginary numbers:
Contrary to what some people might tell you, 'imaginary' numbers are not numbers that only exist in the brains of weird people. Or maybe they are
; all numbers in math are "imaginary" in the sense that you can't touch them or experience them directly. But this is not what people mean when they talk about 'imaginary' numbers. Imaginary numbers are numbers that can be written as a real number times
i, where
i=sqr(-1)
It was invented to be able to calculate with numbers which can't exist.
eg: 5
i = 5 * sqr(-1)
complex numbers are numbers like 3 + 5
i; they are a real number plus an imaginary number.

tbh, I don't care what is said on msn. This is a forum, everybody can read this, so either take your time and explain it correctly and detailed (especially in math cases) or don't
(this whole thread could be as small as a post or 3 when things were explained correctly and detailed in the first place)
