The Square Root of a Negative Number

Mathematicians get the square root of a negative number by use of an imaginary unit. I'm not a mathematician as will become painfully obvious in this post. The problem in concieving the square root of a negative number is that the multiplication of negativity is misunderstood. A negative number multiplied by a negative number does not yield a true positive number, but a double negative number (or more precisely, negativity is squared). If negativity can be multiplied then there must be degrees of negativity. The square root of negative four is thus the square root of 1 degree of negativity two (√-4 = (√-)2).
