The absolute value of zero is zero. The absolute value of any other real number - or even of any other complex number - is different from zero.

Not sure what you're asking, but being the question is in Complex Numbers category, it could be this:If the real part of a complex number is zero, then it is a pure imaginary number.

No. For example the number 1+i. Pure imaginary complex numbers are of the form 0 + a*i, where a is a non-zero real number.

Yes. All real numbers are considered complex numbers, with the imaginary part being equal to zero.

You can describe it as a number defined such that i squared = -1.You can also define the complex plane first, and then describe an imaginary number as a complex number in which the real part is zero.

True. Complex numbers have a real part and an imaginary part. If either one of these is zero, the complex number will be a pure real or a pure imaginary.
