Sorry for the dumb question, I'm not good at mathematics, but:(adsbygoogle = window.adsbygoogle || []).push({});

what is 1/i ?

1/i * 1/i = 1*1 / (i*i) = 1/-1 = -1 ???

If so the number, 1/i has the property that (1/i)^2 = -1 which is the definition of i.

BUT, 1/i is not equal to i because if it did:

1/i * i would be i*i= -1

however,

1/i * i = i / i = 1 ???

So can someone explain what's going on? Where did I make the mistake(s)?

Thanks!
