Negative numbers dont have real roots, so you cannot have a square root of -1

Example: -1 x -1 does not equal -1, so this means you cannot do the same the other way

Real numbers can be positive or negetive and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. Imaginary numbers are numbers that cannot be quantified, like the square root of -1.
