     @iro_miya The post has it backwards - for loops are a functional abstraction of the scary math symbols.

     @iro_miya i've been entirely convinced for years that the whole reason i cannot math is that math notation is just "every variable name is a single letter" times 1000

     @q66 @iro_miya In a way Math is like obfuscated APL and also more toward functional than imperative.

     @karna Yes, he had indeed been crafting the perfect memes even prior to 1969.

     @enigmatico@mk.absturztau.be @iro_miya@mk.absturztau.be do you actually think fedi users can comprehend math above elementary school

     @iro_miya While it's true that you can implement sums using a for loop, it can be optimized using basic summation identities. More specifically
     
     \displaystyle{\sum^k_{n=0}3n = 3\sum^k_{n=0}n = 3\left(\sum^{k-1}_{n=0}n + k\right) = 3\left(\frac{k(k-1)}{2}+k\right)}
     
     Where k \in \mathbb{Z}⁺, k > 0. So you can simply use this generic formula and save yourself a for loop.
     
     The same can be applied to the multiplication as well, although in this case how much computational cost you save will depend on how the machine calculates the factorial.
     
     \displaystyle{\prod^k_{n=1}2n = 2\prod^k_{n=1}n = 2(k!)}

     @iro_miya @acegikmo being able to read math notation in academic papers is a superpower
