Mō ia paheko tau, arā atu anō ētahi paheko e noho whanaunga mai ana. Ina whakaemia ēnei paheko, ka kīia he whānau meka matua. Hei tauira, mō te 3 + 4 = 7, koia nei te katoa o te whānau meka matua:
3 + 4 = 7 4 + 3 = 7 7 − 3 = 4 7 − 4 = 3
For each number operation there are other operations which are related. Together they are called a family of facts. For example, 3 + 4 = 7, 4 + 3 = 7,
7 − 4 = 3, 7 − 3 = 4 is a family of facts.
Tuhia te whānau meka matua mō te 5, te 3, me te 8.
Tuhia ngā tau e ngaro ana i ēnei whānau meka matua.
E kitea ana ngā paheko kōaro i ngā whānau meka matua.
