calculator not working

Thanks Admin, and btw the ! is a factorial sign, it means that number multiplied by all the numbers lower than it up to 1 e.g.

3!=3*2*1=6

I recommend you to remove the exclamation marks because it will not compute and understand

well i did 718-(6x6) and i came up with 682 is this what you meant

I can confirm that this is a bug that will be fixed in the near future, but you can use this input: ncr(718, 6)

$${\left({\frac{{\mathtt{718}}{!}}{{\mathtt{6}}{!}{\mathtt{\,\times\,}}({\mathtt{718}}{\mathtt{\,-\,}}{\mathtt{6}}){!}}}\right)} = {\mathtt{186\,345\,070\,770\,859}}$$
