Sir, said that when a speices goes from low oxidation state to high oxidation state then it looses an electron and we put plus sign.

In this picture Fe is going from +2 oxidation state to +3 state upon loss of electrons. it is shown correct . sir used negative sign to show charge on electron and not oxidation state.

if still doubt persist ask again.
