Question 102959: i stands for iota which equals -1
is it real and rational, real and irrational, or complex?
I'm thinking it is real and rational.-1 is on the number line. I'm thrown off by the word real. Is i classified as a real number, even though it is imaginary?

In mathematics, a complex number is a number of the form
a+%2B+bi
where a and b are real numbers, and i is the imaginary unit, with the property i+%5E2+=-1.
The real+number+a is called the real part of the complex number, and the real+number +b is the imaginary part.
Real numbers may be considered to be complex numbers with an imaginary part of zero; that is, the real number a+is equivalent to the complex number a%2B0i.
In mathematics, the real+numbers may be described informally as numbers that can be given by an infinite decimal representation, such as 2.4871773339….
The real numbers include both rational numbers (such as 42 and −23%2F129), and irrational numbers (such as Pi and the sqrt+%282%29, and can be represented as points along an infinitely long number line.
