WHAKAMĀRAMA

Ko te muku atu i tētahi wāhanga o tētahi tau, huinga rānei. Ko te whiriwhiri i te rahinga ake o tētahi tau i tētahi. Ko te tāpiritanga te paheko kōaro o te tangohanga.

Taking away a part of a number or a set, or finding out how much bigger one number is than another. Addition is the inverse operation of subtraction.

Tauira KŌrero

He aha te mahi i tēnei rapanga pakitau – he tāpiritanga, he tangohanga rānei?

Tangohia te rima i te iwa (9 − 5).

E waru, tangohia te toru, ka rima (8 − 3 = 5).

WhakamĀrama Āpitihanga

Hei whakaatu i te tangohanga me ōna wāhanga:

Koia nei te whānau tangohanga o te iwa:
9 − 9 = 0
9 − 8 = 1
9 − 7 = 2
9 − 6 = 3
9 − 5 = 4
9 − 4 = 5
9 − 3 = 6
9 − 2 = 7
9 − 1 = 8
9 − 0 = 9

Koia nei te whānau meka matua mō te 3, te 5 me te 8:

3 + 5 = 8 5 + 3 = 8

8 − 4 = 3 8 − 3 = 5

Ko te huatango o ētahi tau e rua, koirā te rahinga ake o tētahi o ngā tau i tētahi. Hei tauira, ko te 6 te huatango o te 9 me te 15 nā te mea 15 − 9 = 6.

Ko te whakamahi i te tau māmā tētahi rautaki whaihua hei whakaoti tangohanga. Hei tauira: 54 − 18

He uaua te tango i te 18, nō reira ka tango kē i te 20. He tau māmā te 20. Arā: 54 − 20 = 34

E 2 te rahinga kē atu o te tango i te 20, tērā i te tango i te 18. Nō reira, ka tāpiri atu anō i taua 2:

54 − 18 = (54 − 20) + 2
= 34 + 2
= 36

Ka whakaaturia tēnei rautaki ki te rārangi tau:
