why don't imaginary numbers make so much sense?

    Imaginary numbers are what you feed to the algorithms(of algebraic manipulations), because if you follow through all the logic, the result might come out real.

    For example:
    You know that your formula to find y is: y=a+sqrt(b)+c-sqrt(d)
    But alas b and d are negative.
    So if you invent imaginary numbers your solution might come out real if sqrt(b)=sqrt(d).
