+118723 Do you mean
_7P^3 $$_7P^3$$
OR MORE LIKELY YOU MEAN
^7P_3 $$^7P_3$$
these are both written in LaTex I had to press the [LaTex Formula] button and enter it in there. :)
Now if you want to put it into the calc you can do it like this - I am using the [Calculation] Button
nPr(7,3) $${\left({\frac{{\mathtt{7}}{!}}{({\mathtt{7}}{\mathtt{\,-\,}}{\mathtt{3}}){!}}}\right)} = {\mathtt{210}}$$
