when we define a complex number we say that a number of the form

**z=a+ib**,where a and b are real numbers is called a complex number.

a is called the real part and b is called the imaginary part, but I have a doubt here we know that

**ib**is an imaginary number then why we say only

**b**is the imaginary part of z why not

**ib.**

for example-In z=5+3i why we say

for example-

**3**is the imaginary part of

**z**why not

**3i.**

I am very confused for this please help me...
