since there is no real answer to the square root of any negative number we write i
i=the square root of -1
if you did the square root of -25 you would get 5i which equals to 5 times the square root of -1

The square root of -1 is an imaginary number "i"
Complex math involves using imaginary numbers for signal processing and advanced physics.
A complex number is represented as {Re} + i{Im}, for example 3 + 2i
Engineers call the imaginary number "j" because "i" represents current flow.

Well these seems to be beaten to death but like everyone said you can't find the square of a negative number. In this case it would just be "i" which stands for imginary.
however when you get higher in math you can find imaginary roots of negative numbers i.e. -25 = 5i

If you put square root over negative number, there is no real number for answer.

It is a non-existent number, because you cannot take a square root of a negative number.

i is used to represent the non-real and imaginary square root of negative one.
