For dummies

I learnt something, or is it
I learned something???

I learnt/learned something last week, I know that you are thinking, so, who cares, this is life we are all constantly things every day.
Yes I know that we are, but last week I'm going thru' this Algebra 2 for Dummies book and most of the stuff was just review. I could almost remember going thru the material ten years ago but all of a sudden I turn the page and seem something that didn't ring any bells or conjure any memories.
Ellipticals, this whole topic of finding and graphing the equation for an ellipse, and hyperbolic function was new to me.
So yes, I am happy,

I have learned/learnt something.
