Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 9 i te 20, ka 11.

$$E=13\times 11$$

Whakareatia te 13 ki te 11, ka 143.

$$E=143$$

Whakaarohia te whārite tuarua. Whakareatia te 18 ki te 0, ka 0.

$$F=0$$

Whakaarohia te whārite tuatoru. Whakareatia te 8 ki te 0, ka 0.

$$a=9-0$$

Tangohia te 0 i te 9, ka 9.

$$a=9$$

Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=9$$

Whakaarohia te whārite tuarima. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$c=9$$

Whakaarohia te whārite (6). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$d=9$$

Kua oti te pūnaha te whakatau.

$$E=143 F=0 a=9 b=9 c=9 d=9$$
