What math theorems would you like to go back and learn again

trying too hard

For me it would be 1+1 = 2. I wish I could remember how it was before I knew arithmetic. I could feel like a brainlet and perhaps develop some empathy for the engineers around here.

Seriously, do any of you remember? How it was before you knew any math? If I try to remember that far back it is just like a black hole ate my memories. I don't remember it. All memories I have are from after I knew arithmetic. Fucking weird.

>For me it's L'Hospitals rule, it was so comfy and easy to use.
Using a theorem you're unable to prove in a 100% rigorous way and in its most general context is pure retardation. And l'Hôpital's rule is not easy to prove.

I think I was ten when I realized, for myself, the distributivity of multiplication over addition. I thought myself quite the genius.

I discovered it independently, in a summer holiday thinking about math at a bored moment. This was well before I knew algebra, so I did not know how to phrase it as a general rule; but I nevertheless understood the pattern in a wordless way. I was both awed, and very impressed with myself.

none of them? if you liked learning something go open the book and learn it for a second, third, etc time. it's good for your foundations

Also straight learning Integration

Taylor's expansion was awesome.

>Not a theorem but a really elegant question
Given two tangent to a conic. From a point of the contact chord are drawn their parallel lines, which make a parallelogram.
What is the envelope of the parallelogram's diagonals?
