Imaginary Numbers
Integers are whole numbers that can be positive.
In contrast, their values can also be negative.
On the x-axis, natural numbers are to the right of the zero.
On the vertical y-axis, they are above the zero as far as they can go.
You may think this question is moot:
With a negative number, how do you find its square root?
In a quadratic formula, if the discriminate is less than zero,
there are no real roots. So where do you go?
This put many early mathematicians in a quandary.
Somebody came along and invented numbers that are imaginary.
