minus-squareInternetCitizen2@lemmy.worldOPlinkfedilinkarrow-up0·1 month agoIn case anyone wondering factorial is n! = n * n-1 * n-2 * … * 3 * 2 * 1
minus-squareweker01@sh.itjust.workslinkfedilinkarrow-up0·1 month agoErm. In what world do you live that the precedent in your expression is right? In all languages and countries I know multiplication binds more strongly than addition. So what you wrote would be n^2 - n - 2n - 3n…
minus-squareInternetCitizen2@lemmy.worldOPlinkfedilinkarrow-up0·1 month agoI wrote it correctly. It is the definition of a factorial.
minus-squareweker01@sh.itjust.workslinkfedilinkarrow-up0·1 month agoNo, correctly it would be n * (n-1) * (n-2) * … * 3 * 2* 1 Or the actual recursive definition 1! = 1 n! = (n-1)! * n
In case anyone wondering factorial is
n! = n * n-1 * n-2 * … * 3 * 2 * 1

Or the actual recursive definition
1! = 1
n! = (n-1)! * n
