What do you mean by 0!=1 here? It reads as the integers zero and one are not equal, which is true. I'm struggling to guess what established rules that could break.
- rmadriz 4y ago> It reads as the integers zero and one are not equal, which is true That's not what 0!=1 means in math, the ! means factorial, which is to multiply by decreasing positive integers. Here's the definition: n! = n x (n -1) x (n - 2) x . . . x 2 x 1 So, for people starting to learn calculus/math, being told that 0!=1 makes no sense
- JonChesterfield 4y agoAh. ! for factorial was not an obvious parse. I suspect it has alternative meanings in mathematics as well.
