Hey,
by saying "between", you give us, the tutors, to understand that square root of -4, in your opinion, is a real number.

Meanwhile, it is not so.

Sqrt(-4) does not exist among real numbers.

sqrt(-4) is a COMPLEX number.

But among COMPLEX NUMBERS, there is NO relation "BETWEEN".

So, be careful when use mathematical terms and talks to others on mathematical subjects.

Or, better to say, be KNOWLEDGEABLE !

Happy learning in Math !
