It is by convention equal to the multiplicative identity 1 , just as the empty sum—the result of adding no numbers ... It is useful when learning recursion to have a toy problem like factorial be presented ... NettetIs there a factorial but for addition? So 4! is 24 but is there something similar so you just add 4,3,2,1? Well, there's summation notation. It looks like an uppercase sigma with something like i=1 at the bottom and i next to it with the last number of the term at the top like this. Awesome, thank you.
Has this conjecture been proven/disproven/found before?
