    The ignorance is entirely yours.  Mathematicians do "explain" what i is,

    You might say i²=-1 without understanding (which seems fairly likely),
    more educated people say it with full understanding.

    Absolutely not.

    Les mathématiciens n'expliquent rien du tout.

    Here is a good example of some interesting videos about the complex
    numbers from a historical perspective:

    Ils partent de l'hypothèse i²=-1 ou de l'hypothèse x²+1=0.

    Mais ils n'expliquent rien du tout.

    MOI, j'explique. Le monde des imaginaires est tel que i^x=-1 quelque
    soit x.

    Il va de soi que si j'explique quelque chose, cela ne plait pas du tout.

    C'est l'histoire de ma vie.
