"New" Rap- Complex Numbers

I didn't write any new math raps this week but here is another that I wrote for my Algebra 2 class last semester.

Lookin at the complex numbers,
You say what is that i?
Just give me a second
You’ll say it’s easy as pie.
See i is the square root
Of negative one.
So if it’s on the bottom
Then the problem’s not done.
If it is on the bottom
With an add or subtract.
We must use the conjugate
And that is a fact.
When you simplify the i’s
Just divide it by four.
Because the sequence repeats
When you remember it you’ll soar.
Just know that i is i
And i squared is negative one.
Then i cubed is negative i
Which leaves i fourth as just one.
