if i is a number then what is its numerical value?



i is the unit imaginary part of complex number , but there is a question which it is mixed me probably i missed the definition of a number , wolfram alpha i is assumed to be a number , and others assumed it to be variable because it satisfies i2 =+i or i then my question here :



Question:

Is i a number then what is it's value ?


Answer



Asking what's the value of i is like asking what's the value of 2. And, just like i2 has two square roots, i and i, 22 has two square roots, 2, and 2.



And yes, it is a number, not a variable.
