well
"*"(3,2) works but "*"(3,2,3) does not. You should now be able to
figure out the logic. It is related to the number of arguments that
make sense.

Hi friends, I am aware of the function "-"() which acts as minus in
ordinary computations. For example:
"-"(3, 1)
[1] 2
However what is the meaning of
"-"(3)
[1] -3
I was expecting R to generate some error as it does for "*"(3). What
is the logic for that calculation?
Thanks,
