why is this happening?


? Vecsmall([1]) - Vecsmall([1])
  ***   at top-level: Vecsmall([1])-Vecsmall([1])
  ***                              ^--------------
  *** _-_: forbidden addition t_VECSMALL + t_VECSMALL.
  ***   Break loop: type 'break' to go back to GP prompt
break>

Can anyone explain why this won't work?

Can't we subtract any element in GP Pari from itself and get 0 or null ?
