ClO^- (aq) + H₂O (l)  HClO (aq) + OH^- (aq)
I^- + HClO (aq)  HlO (aq) + Cl^- (aq)
OH^- (aq) + HlO (aq)  H₂O (l) + IO^- (aq)

ClO^- (aq) + H₂O (l)  HClO (aq) + OH^- (aq)
I^- + HClO (aq)  HlO (aq) + Cl^- (aq)
OH^- (aq) + HlO (aq)  H₂O (l) + IO^- (aq)

ClO^- (aq) + I^- (aq)  Cl^- + IO^- (aq)

Am I supposed to cross out the intermediates per TWO reactions (i.e. first reaction cancels with second reaction then second reaction cancels with third reaction) or did I do it right above by cancelling everything that were opposites on both sides?
