Mehemea he nui ake i te kotahi ngā paheko i roto i tētahi tātaitanga, me mātua whai te raupapa paheko e tika ana. Arā, me whakaoti ngā taiapa i te tuatahi, kātahi ko ngā taupū, ko ngā whakawehenga, me ngā whakareatanga, ko ngā tāpiritanga, me ngā tangohanga. Hei tauira:
3 + 4 × 2 = 3 + 8 (te whakareatanga i te tuatahi)
= 11
(3 + 4) × 2 = 7 × 2 (ngā taiapa i te tuatahi)
= 14
