Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 1862 mai i ngā taha e rua.

$$x=4-1862$$

Tangohia te 1862 i te 4, ka -1858.

$$x=-1858$$

Whakaarohia te whārite tuarua. Tāpirihia te -8 ki te 7, ka -1.

$$y=-1$$

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

$$z=-1$$

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

$$a=-1$$

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

$$b=-1$$

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

$$c=-1$$

Whakaarohia te whārite (7). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$d=-1$$

Kua oti te pūnaha te whakatau.

$$x=-1858 y=-1 z=-1 a=-1 b=-1 c=-1 d=-1$$
