The imaginary number (i) is defined as the square root of -1. If you multiply i by i you get -1
There are no numbers that you can multiply by itself that would make a negative number.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
every number is a real number....except imaginary.......and this is the amin reason for we can say that real number is real because its not imaginary....

If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.

If the imaginary part of z is 0, then z is simply a real number and if you multiply by 1 which is the identity in multiplication of real numbers, you of course will still have a real number with imaginary part 0

an imaginary number is imaginary so no (i guess) this answer kind of sucks
A real number is a number that does not have an imaginary component. There is no imaginary component in -17, so it is a real number.
Yes. If you multiply X + iY by X - iY you get X2 + Y2. The imaginary parts cancel out.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.

It can be either.
Real part of the result = real part of first number + real part of second number Imaginary part of the result = imaginary part of first number + imaginary part of second number
